Replaceable Light Source Information; Federal Motor Vehicle
Safety Standards Lamps, Reflective Devices, and Associated Equipment
AGENCY: National Highway Traffic Safety Administration (NHTSA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This document amends the Federal motor vehicle safety standard
on lighting to allow high intensity discharge (HID) light sources to be
used in replaceable bulb headlamp systems, in addition to their
presently allowed use in integral beam headlamp systems. Adoption of
this amendment requires corresponding amendments to part 564, the
regulation under which Docket No. 93-11 was established as a depository
for replaceable light source information. However, if the life of the
light source approaches that of the vehicle, as is the case with HIDs,
interchangeability will no longer be so important. Therefore, NHTSA is
adding Appendix B to part 564 which allows a manufacturer to submit
fewer items of dimensional information if it can demonstrate that the
rated laboratory life of its light source is not less than 2,000 hours.
DATES: Effective Date: The amendments to the Code of Federal
Regulations, and the requirements of the amendments, are effective June
6, 1996.
Petition Date: Petitions for reconsideration must be received not
later than June 21, 1996.
FOR FURTHER INFORMATION CONTACT: Kenneth O. Hardie, Office of
Rulemaking (202-366-6987).
SUPPLEMENTARY INFORMATION: On June 19, 1995, NHTSA published a notice
in the Federal Register to initiate rulemaking that would amend
Standard No. 108 so as to allow replaceable bulb headlamps to
incorporate short arc discharge light sources (60 FR 31939).
As NHTSA noted in the NPRM, short arc discharge headlamp systems
are commonly referred to as ``high intensity discharge'' (HID) systems.
Presently, the only HID application in production for lamps covered by
Standard No. 108 is in headlamps, and the only way HID headlamps can be
used under Standard No. 108 is in an ``integral beam headlighting
system'' (Section S7.4). Thus, today, HID headlamps are comprised of a
headlamp body (including reflector and lens), a small transparent
envelope containing a specific mixture of gases under high pressure
(the discharge bulb), and an electronic ballast to convert low voltage
direct current to a controlled output high voltage direct or
alternating current to drive the discharge bulb.
However, by definition (S4), an integral beam headlamp (including
those with HID light sources) is one with an ``integral and indivisible
optical assembly'', and a headlamp that is ``not a replaceable bulb
headlamp * * *.'' In the event of damage to one component, such as the
lens, the entire unit, ballast and all, must be replaced. The cost to
replace an integral beam HID headlamp is substantially higher than the
cost of replacing a more conventional headlamp. The initial HID
headlamp permitted (as a result of NHTSA-initiated amendments to
Standard No. 108 to facilitate their introduction) was an integral-type
design. At the time, it was unknown how to define HID sources as
replaceable bulb light sources. The agency is now furthering HID
headlamp technology by defining HID's as ``replaceable light sources'',
so that headlamp components may be individually replaced. This
amendment to Standard No. 108 means that a vehicle manufacturer wishing
to offer HID headlamps now has a choice between two types, integral and
replaceable light source.
Comments in support of the NPRM were received from the American
Automobile Manufacturers Association (AAMA), Ford Motor Co., Hella,
Inc., Koito Manufacturing Co. Ltd., OSRAM Sylvania, Inc. (OSI), and
Stanley Electronic Co., Inc. Comments opposing the proposal were
received from the Insurance Institute for Highway Safety (IIHS) and
Advocates for Highway and Auto Safety (Advocates).
Proposed Amendments to Standard No. 108
S4 Definitions. NHTSA proposed to add a definition of ``filament''
to read:
Filament means that part of the light source or light emitting
element(s), such as a resistive element, the excited portion of a
specific mixture of gases under pressure, or any part of other
energy conversion sources, that generates radiant energy which can
be seen.
No comments were received on this issue and the proposed definition is
adopted.
Paragraph S7.7(i). The NPRM proposed amendments to paragraph
S7.7(i). Under the final rule published on November 28, 1995 (60 FR
58522), transferring HB type light sources to part 564, paragraph
S7.7(i) became paragraph S7.7(b). Under the final rule published today,
paragraph S7.7(b) becomes S7.7(d). The following summary of the
proposal adopts the nomenclature of the final rule, which does not
significantly differ from the proposal.
Paragraph S7.7(d) discusses the procedures for measuring maximum
power and luminous flux. This is followed by two new subparagraphs, the
first of which, S7.7(d)(1), applies specifically to seasoning
requirements for light sources with resistive element type filaments
and luminous flux measurement requirements for HB Type bulbs. The
second, S7.7(d)(2), applies to seasoning requirements for light sources
using excited gas mixtures as filaments or discharge arcs and
associated luminous flux measurement. As for seasoning of light sources
using other energy conversion sources, NHTSA will address this issue
when industry has identified such sources.
OSI recommended that the seasoning for resistive and excited-gas
light sources (including ballasts) should be one percent of rated life,
as set forth in SAE Recommended Practice J2009 FEB93 Discharge Forward
Lighting Systems (hereafter ``SAE J2009''). Ford also recommended that
seasoning for excited gas light sources (including ballast) be in
accordance with SAE J2009. Additionally, Ford recommended that
seasoning for resistive element type filaments be in accordance with
SAE J1383 APR85. NHTSA notes that its proposed amendments affecting
``seasoning'' are consistent with the OSI and Ford recommendations.
Ford found proposed paragraph S7.7(i) confusing and it suggested
changes which it felt would clarify NHTSA's intent. NHTSA concurs, and
has rewritten the provision as S7.7(b) (In addition to recommending
specific
[[Page 20498]]
requirements for the measurement of luminous flux for a light source
with a resistive element type filament, Ford did not object to the
NHTSA proposal to specifically cite seasoning requirements for light
sources using an excited gas mixture).
Regarding proposed paragraph S7.7(l)(7) which would require the
date of manufacture to be placed on the light source, Ford asked that
it not be adopted as it provides no safety benefit and because Standard
No. 108 does not require date of manufacture marking for any other
lamps or lighting equipment. NHTSA concurs, and the proposal is not
adopted.
Readers should note that proposed new paragraph S7.7(l) is adopted
as paragraph S7.7(e). New section S7.7(f) is added to state that, for
light sources that use light generated by gaseous discharge lighting
sources, seasoning shall be in accordance with section 4.0, and the
``rated laboratory life'' shall be determined in accordance with
sections 4.3 and 4.9 of SAE J2009.
S8 Tests and Procedures for Integral Beam and Replaceable Bulb
Headlighting Systems. In the NPRM, NHTSA proposed adding ``specific gas
mixture'' type light sources in the tests specified in S8 to replace
``non-filament type.'' There was no objection and S8 is amended as
proposed.
Other Issues Associated with Short Arc Discharge Lighting Systems.
The only regulatory requirement that NHTSA proposed that addressed the
issue of electrical shock was the marking of the ballast with an
appropriate warning. Stanley recommended the adoption of a universally
agreed upon marking system such as specified by the International
Standards Organization (ISO). However, NHTSA wishes to allow
manufacturers wide latitude in choosing their warnings regarding
electrical shock and has not followed Stanley's suggestion in the final
rule.
Proposed Amendments to Part 564
General. Ford would replace all references to ``filament'' with
``filament or discharge arc.'' NHTSA agrees, and this has been done
when the text could specifically refer to either. Also as indicated
previously, the definition of ``filament'' that was proposed to be
added to Standard No. 108, and it applies to part 564 by virtue of
Section 564.4 which incorporates definitions used in other NHTSA
regulations.
Section 564.2 Purpose. Ford recommended that this section not be
revised because both Appendix A and Appendix B have a common purpose;
``they merely accomplish it by requiring varying degrees of information
detail dependent upon the rated laboratory life of the light source.''
NHTSA disagrees; the intended purposes of Appendix A and Appendix B are
different. One purpose of the former is to assure that replacement
light sources are available and interchangeable. This is not a purpose
of Appendix B because long-life light sources need not be manufactured
for interchangeability purposes by many different aftermarket
suppliers. Because light sources with specifications filed under
Appendix B are expected to last the life of the vehicle, component
replacement would be necessitated primarily by damage. Thus it is
unlikely that the low demand for replacement components would be met by
other than manufacturers of the original equipment devices. This
distinction from Appendix A requires two different statements of
regulatory purposes in section 564.2.
Finally, Appendix B allows manufacturers to retain ballast design
parameters that may include proprietary manufacturing specifications,
whereas Appendix A requires disclosure of such aspects as they relate
to interchangeability.
Paragraph 564.5(a). Under the proposal, relevant manufacturers must
``furnish the information specified in appendix A or appendix B.'' Ford
suggested that this implied that manufacturers could file under either
Appendix when filing under Appendix B is allowable only for long-life
light sources. NHTSA has made an editorial change to clarify that
Appendix B is available only for long-life light sources, while both
Appendices are available for long- life light source information.
Appendix B. Commenters concurred with NHTSA's proposed benchmark
that not less than 2,000 hours of rated laboratory life is a suitable
designation of a long-life light source. In accordance with the
proposal, in the final rule the manufacturer of such a light source may
provide the lesser amount of information that will be required by
Appendix B, but, at its option, can make its submission under Appendix
A. In either event, a replaceable light source which is the subject of
information submitted to Docket No. 93-11 is required to comply with
Standard No. 108.
Stanley commented that a clear definition of ``life'' was not
provided in the NPRM, and recommended that ``life'' of a light source
be defined in terms of luminous flux maintenance. NHTSA concurs that an
explanation is desirable, since Standard No. 108 and Part 564 both
indicate that manufacturers may optionally furnish the information
specified in Appendix B, if the ``rated average laboratory life'' is
not less than 2,000 hours. The SAE has addressed this issue in sections
4.3 and 4.9 of SAE J2009. These sections specify procedures and tests
to determine life of the total HID system measured in both hours and
starting cycles. NHTSA is adopting the term used there, ``rated
laboratory life.'' In so doing, it also examined the definition of
``rated average laboratory life'' which appears in SAE Standard J1383
JUN90. It found that SAE J1383 JUN90 was suitable for incandescent
light sources where lumen drop off occurs at a relatively steady rate
over life, but that HID system lumens drop rapidly during the initial
burning hours and then, later, tend toward a more level rate of drop.
In Koito's view, Appendix B is not necessary. It believes that all
light source submittals to part 564, including HIDs, and regardless of
the rated laboratory life, should contain the information required in
Appendix A. It indicated that the life in hours of an HID light source
will vary with the ballasts combined with it. Therefore, life in hours
for an HID light source is essentially meaningless if the original
ballast is changed to another type of ballast. NHTSA understands this.
It is for this reason that NHTSA is adopting the language proposed in
the NPRM that Item III of Appendix B specifies the rated laboratory
life of the light source/ballast combination instead of that of the
light source alone. Item IV of Appendix B of this final rule reflects
this requirement. Appendix B was specifically intended to accommodate
all ballasts that are functionally interchangeable with a light source
but different in design. New paragraph S7.7(e)(4) of Standard No. 108,
adopted in this final rule, requires that each ballast filed with a
light source bear permanent markings that indicate the rated laboratory
life of the combination. Any part 564 submittal for a light source
requiring ballasts for operation must include information that
specifically identifies all ballasts that will be used with the light
source. Substitution of a ballast other than that identified with the
light source in part 564 is not permitted.
It is important that ballast information be submitted. NHTSA
considers the electronic ballast along with the transparent envelope
containing a specific mixture of gases under pressure (the discharge
bulb) to be an integral part of the light source system, although the
bulb and ballast may be separate components. Furthermore, in
determining compliance with Standard No. 108, testing of the light
source
[[Page 20499]]
without a designated ballast would be difficult if not impossible.
NHTSA has decided not to act upon Koito's recommendation that all
light source submittals (including HID) be required to fulfill all
informational requirements of Appendix A. The intent of Appendix A is
to ensure that sufficient technical information is available to
replacement light source manufacturers so that they may manufacture
identical replacement light sources. NHTSA has decided that requiring
the Appendix B submitter to provide all the information required in
Appendix A is unnecessary if the manufacturer provides rated laboratory
life data supporting a light source and ballast life of 2,000 hours or
more.
Ford recommended that Section I of Appendix A be added to Appendix
B (``Filament Position Dimensions and Tolerances Using Either Direct
Filament Dimensions or the Three Dimensional Filament Tolerance Box'').
Ford also recommended that Appendix B require specification of the
electrode position dimensions and tolerances for light sources using
excited gas mixtures as filaments. Ford stated that the mid-point of
the electrode separation distance would provide a comparable dimension
``A'' of Figure 8 to be utilized in Standard No. 108's section S9
Deflection test for replaceable light sources. NHTSA concurs with this
recommendation since, as Ford stated, the mid-point of the electrode
separation distance would provide a comparable dimension ``A'' which is
required to support the bulb deflection test for replaceable light
sources (S9). NHTSA has accordingly amended Section I of Appendix B as
adopted.
Finally, the reader should note that the conforming amendments to
paragraphs 564.5(a) and (c) reflect the agency's recent amendment of
paragraph S7.7 of Standard No. 108 and 564.5(a) and (c) to transfer HB
type replaceable light sources to Docket No. 93-11 (November 28, 1995;
60 FR 58522).
Comments in Opposition
IIHS opposed the rulemaking action because HID light sources are
more expensive to replace than other light sources and recommended that
the agency not permit the use of increasingly expensive lighting
systems on motor vehicles without conducting a parallel rulemaking to
reinstate a no- damage 5 mph bumper standard. Advocates, too, believed
that the replacement cost for HID headlamp systems ought to be a
central consideration of this rulemaking. NHTSA notes that HID light
sources are permitted in integral beam lighting systems, and will
continue to be so used even if they are not permitted in replaceable
bulb systems. However, the proposal to allow them in such systems is
being adopted because there are no safety disbenefits in allowing them.
The use of replaceable light source HID lighting systems as an
alternative to non-replaceable ones or to resistive element type
filament lighting systems is an issue of the marketplace, not of
safety.
Advocates disagreed with NHTSA that this rulemaking would reduce
costs both to manufacturers and consumers. In its view, NHTSA's
rationale for cost reduction is based upon the fact that HID headlamps
might not have to be replaced for the life of the vehicle and
consequently is not an adequate evaluation of the costs and benefits
accruing to consumers from the institution of HID headlamp systems.
NHTSA's rationale for cost reduction is intended in the context of
HID headlamp systems. In an integral beam system using HIDs, all
headlamp parts must be replaced when a component fails or is damaged,
even for something as simple as a cracked lens. Allowing HID's to be
used in replaceable bulb headlamp systems would permit separability and
the replacement of individual components at significant cost savings to
the consumer. Repair costs for damaged HID headlamps ought to be
significantly reduced if lamp bodies, discharge bulbs and ballasts can
be individually serviced, instead of being replaced as part of a
headlamp assembly. In addition, it is probable that minor damage would
be repaired (such as a cracked lens) that could degrade headlamp
performance if there is an economic incentive not to defer correction
until required to do so, either by failing performance or state motor
vehicle inspection.
Advocates also argued that the rulemaking was mischaracterized as
``non-significant.'' The rulemaking is properly characterized under DOT
policies and procedures. The final rule prescribes an alternative,
optional, headlighting system, and results in no additional costs or
burdens upon any regulated person or upon the public.
Finally, Advocates disagreed with the agency's decision not to
regulate ultraviolet radiation (UV) and electric shock, and recommended
that a supplementary NPRM be issued addressing the possible threat to
human health and safety through UV emissions and high voltages.
There appears to be no current need to do so, other than requiring
a warning marking on the ballast. NHTSA addressed these concerns in the
preamble to the proposal (see 60 FR at 31942). In that discussion,
NHTSA noted that SAE J2009 recognizes UV radiation and electric shock
as potential safety hazards. To address the hazard of UV radiation, the
lighting community has developed HID bulbs that include an additional
transparent envelope which is a UV filter. Other innovative design
solutions are being considered to prevent UV emissions. The need for
high voltage shock safety is also recognized by the SAE document. These
are design and testing issues for the manufacturer. NHTSA will monitor
them and propose rulemaking if it appears to be required for health and
safety.
Effective Date
Since the final rule does not impose any additional burden and is
intended to afford an alternative to existing requirements, it is
hereby found that an effective date earlier than 180 days after
issuance of the final rule is in the public interest. The final rule
(i.e., the amendments to the Code of Federal Regulations and the
requirements specified therein) is effective 30 days after its
publication in the Federal Register.
Rulemaking Analyses
Executive Order 12866 and DOT Regulatory Policies and Procedures
This rulemaking action has not been reviewed under Executive Order
12866. It has been determined that the rulemaking action is not
significant under Department of Transportation regulatory policies and
procedures. The effect of the rulemaking action is to allow an
alternative headlighting system. It will not impose any additional
burden upon any person. The final rule will reduce costs both to
manufacturers and consumers. Because ballasts will no longer have to be
integral with the light source, manufacturers may use a simpler, less
expensive connector. Consumers may replace separate elements of an HID-
replaceable light source headlamp system as compared with the present
regulation which requires replacement of the whole unit. Impacts of the
rule are, therefore, so minimal as not to warrant preparation of a full
regulatory evaluation.
Regulatory Flexibility Act
The agency has also considered the effects of this rulemaking
action in relation to the Regulatory Flexibility Act. I certify that
this rulemaking action would not have a significant economic
[[Page 20500]]
effect upon a substantial number of small entities. Motor vehicle and
lighting equipment manufacturers are generally not small businesses
within the meaning of the Regulatory Flexibility Act. Further, small
organizations and governmental jurisdictions will not be significantly
affected as the price of new motor vehicles will not be impacted.
Accordingly, no Regulatory Flexibility Analysis has been prepared.
Executive Order 12612 (Federalism)
This action has been analyzed in accordance with the principles and
criteria contained in Executive Order 12612 on ``Federalism.'' It has
been determined that the rulemaking action does not have sufficient
federalism implications to warrant the preparation of a Federalism
Assessment.
National Environmental Policy Act
NHTSA has analyzed this rulemaking action for purposes of the
National Environmental Policy Act. The rulemaking action will not have
a significant effect upon the environment as it does not affect the
present method of manufacturing motor vehicle lighting equipment.
Civil Justice Reform
This rulemaking action will not have any retroactive effect. Under
49 U.S.C. 30103, whenever a Federal motor vehicle safety standard is in
effect, a state may not adopt or maintain a safety standard applicable
to the same aspect of performance which is not identical to the Federal
standard. Under 49 U.S.C. 30163, a procedure is set forth for judicial
review of final rules establishing, amending, or revoking Federal motor
vehicle safety standards. That section does not require submission of a
petition for reconsideration or other administrative proceedings before
parties may file suit in court.
Paperwork Reduction Act
The reporting and record keeping requirement associated with part
564 have been approved by the Office and Management and Budget in
accordance with 44 U.S.C. chapter 35. The OMB control number is 2127-
0563.

(a) If other than an HB Type, the light source shall be marked with
the bulb marking designation specified for it in compliance with
Appendix A or Appendix B of part 564 of this chapter. The base of each
HB Type shall be marked with its HB Type designation. Each replaceable
light source shall also be marked with the symbol DOT and with a name
or trademark in accordance with paragraph S7.2.
(b) The measurement of maximum power and luminous flux that is
submitted in compliance with Appendix A or Appendix B of part 564 of
this chapter shall be made in accordance with this paragraph. The
filament or discharge arc shall be seasoned before measurement of
either. Measurement shall be made with the direct current test voltage
regulated within one quarter of one percent. The test voltage shall be
12.8v. The measurement of luminous flux shall be in accordance with the
Illuminating Engineering Society of North America, LM-45, IES Approved
Method for Electrical and Photometric Measurements of General Service
Incandescent Filament Lamps (April 1980); shall be made with the black
cap installed on Type HB1, Type HB2, Type HB4, and Type HB5, and on any
other replaceable light source so designed; and shall be made with the
electrical conductor and light source base shrouded with an opaque
white cover, except for the portion normally located within the
interior of the lamp housing. The measurement of luminous flux for the
Types HB3 and HB4 shall be made with the base covered with a white
cover as shown in the drawings for Types HB3 and HB4 filed in Docket
No. 93-11. (The white cover is used to eliminate the likelihood of
incorrect lumen measurement that will occur should the reflectance of
the light source base and electrical connector be low).
(c) The capsule, lead wires and/or terminals, and seal on each Type
HB1, Type HB3, Type HB4, and Type HB5 light source, and on any other
replaceable light source which uses a seal, shall be installed in a
pressure chamber as shown in Figure 25 so as to provide an airtight
seal. The diameter of the aperture in Figure 25 on a replaceable light
source (other than an HB Type) shall be that dimension furnished for
such light source in compliance with Appendix A or Appendix B of part
564 of this chapter. An airtight seal exists when no air bubbles appear
on the low pressure (connector) side after the light source has been
immersed in water for one minute while inserted in a cylindrical
aperture specified for the light source, and subjected to an air
pressure of 70kPa (10 P.S.I.G.) on the glass capsule side.
(d) The measurement of maximum power and luminous flux that is
submitted in compliance with section VII of Appendix A of part 564 of
this chapter, or section IV of Appendix B of part 564 of this chapter,
shall be made with the direct current test voltage regulated within one
quarter of one percent. The test voltage shall be 12.8v. The
measurement of luminous flux shall be in accordance with the
Illuminating Engineering Society of North America, LM 45; IES Approved
Method for Electrical and Photometric Measurements of General Service
Incandescent Filament Lamps (April 1980). The filament of a replaceable
light source shall be seasoned before such measurement. The white
covers are used to eliminate the likelihood of incorrect lumens
measurement that will occur should the reflectance of the light source
base and electrical connector be low.
(1) For a light source with a resistive element type filament,
seasoning of the light source shall be made in accordance with section
2.9 of SAE Standard J1383 APR85 Performance Requirements for Motor
Vehicle Headlamps. The measurement of luminous flux shall be made with
the black cap installed on Type HB1, Type HB2, Type HB4, and Type HB5
light sources, and on any other replaceable light source so designed,
and shall be made with the electrical conductor and light source base
shrouded with an opaque white colored cover, except for the portion
normally located within the interior of the lamp housing. The
measurement of luminous flux for Type HB3 and Type HB4 shall be made
with the base covered with the white cover shown in the drawings for
Types HB3 and HB4 filed in Docket No. 93-11.
(2) For a light source using excited gas mixtures as a filament or
discharge arc, seasoning of the light source system, including any
ballast required for its operation, shall be made in accordance with
section 4.0 of SAE Recommended Practice J2009 FEB93 Discharge Forward
Lighting Systems. With the test voltage applied to the ballast input
terminals, the measurement of luminous flux shall be made with the
black cap installed, if so designed, and shall be made with an opaque
white colored cover, except for the portion normally located within the
interior of the lamp housing.
(e) If a ballast is required for operation, each ballast shall bear
the following permanent markings:
(1) Name or logo of ballast manufacturer;
(2) Ballast part number or unique identification;
(3) Part number or other unique identification of the light source
for which the ballast is designed;
(4) Rated laboratory life of the light source/ballast combination,
if the information for the light source has been filed in Appendix B of
part 564 of this chapter;
(5) A warning that ballast output voltage presents the potential
for severe electrical shock that could lead to permanent injury or
death;
(6) Ballast output power in watts and output voltage in rms volts
AC or DC; and
(7) The symbol `DOT'.''
(f) For light sources that use excited gas mixtures as a filament
or discharge arc, the ``rated laboratory life'' shall be determined in
accordance with sections 4.3 and 4.9 of SAE Recommended Practice J2009
FEB93 Forward Discharge Lighting Systems.
(g) After the force deflection test conducted in accordance with
S9, the permanent deflection of the glass envelope shall not exceed
0.13 mm in the direction of the applied force.
