[Docket No. 94-12; Notice 1]
Mercedes-Benz of North America, Inc.; Receipt of Petition for
Determination of Inconsequential Noncompliance
Mercedes-Benz of North America, Inc. (Mercedes) of Montvale, New
Jersey has determined that the headlamps on some of its vehicles fail
to comply with the lens bonding requirements of 49 CFR 571.108, Motor
Vehicle Safety Standard No. 108, ``Lamps, Reflective Devices and
Associated Equipment,'' and has filed an appropriate report pursuant to
49 CFR Part 573, ``Defect and Noncompliance Reports.'' Mercedes has
also petitioned to be exempted from the notification and remedy
requirements of the National Traffic and Motor Vehicle Safety Act (15
U.S.C. 1381 et seq.) on the basis that the noncompliance is
inconsequential as it relates to motor vehicle safety.
This notice of receipt of a petition is published under section 157
of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1417)
and does not represent any agency decision or other exercise of
judgment concerning the merits of the petition.
Paragraph S4 of FMVSS No. 108 defines ``replaceable bulb headlamp''
as one that is comprised of a bonded lens and reflector assembly.
During the period of August 1991 to December 1993, Mercedes
produced approximately 46,000 Mercedes-Benz vehicles for sale in the
United States in which the lenses were securely clipped onto their
reflectors as an assembly, but not bonded as required by FMVSS No. 108.
These vehicles included approximately 35,925 S-Class, 7,379 E-Class,
and 2,632 C-Class models. In addition, approximately 1,873 noncompliant
replacement part headlamps and approximately 1,147 noncompliant
replacement part headlamp lenses were sold to Mercedes-Benz
dealerships.
Mercedes supports its petition for inconsequential noncompliance
with the following:
1. Damaged Lenses Will Be Replaced With Complying Headlamp
Assemblies
Based on the number of replacement lenses sold in Model Years
1991-92, (Mercedes) estimates that approximately 500 lenses are
replaced each year in the subject vehicles.
Thus, the number of vehicles involved is relatively low.
Effective November 2, 1993, (Mercedes) no longer sells lenses as
a replacement part. This means that no source for replacement lenses
now exists. Therefore, when lenses are damaged in the future, the
owner's only recourse will be to replace the entire headlamp
assembly that complies with Standard 108.
In the unlikely event that a noncomplying aftermarket lens
market were developed for the 46,000 vehicles produced, their use
would be restricted by state inspection laws. At the present time,
approximately two-thirds of all states have periodic inspection
programs. As evidenced by * * * state vehicle regulations (which
Mercedes included with its petition and are contained in the
Docket), replacement headlamp lenses are required to keep the
headlamp in compliance with Standard 108. It is our understanding
that State Inspection garages routinely reject cars if their
headlamp lenses do not bear the ``DOT'' marking, since the lack of
``DOT'' quickly identifies the headlamp as a non-U.S. unit.
Therefore, in the unlikely event that a vehicle owner replaces a
damaged lens with a noncomplying aftermarket lens rather than a
complying headlamp assembly, the vehicle will fail inspection in
most states.
2. Headlamp Aim Not Affected
In a recently published Federal Register notice (Docket 93-57)
requesting comments on the subject of bonded versus unbonded
headlamps, NHTSA stated:
In previous denials of petitions to allow removable headlamp
lenses, NHTSA argued that mechanical aiming of lamps with lens-
mounted aiming pads could be affected by any change of the alignment
relationship established between lenses and reflectors at the time
of manufacture. Thus, alteration of the original alignment during
lens replacement could misaim the beam. (58 FR. 42,924 (August 12,
1993.)
This concern is not relevant here because the vehicles in
question contain on-board aiming devices (vehicle headlamp aiming
devices). No aiming pads are needed in such advanced technology.
Since the lens does not participate in the aiming of the headlamp,
aiming cannot be affected by misalignment of the lens during lens
replacement in the Mercedes system.
3. Headlamp Beam Formation Not Affected
In the same Federal Register notice, NHTSA expressed concern
that replacement lenses may alter the headlamp beam formation due to
the fluting (prescription) of the lens. Several factors assure
photometric compliance with Standard 108 for the Mercedes-Benz
unbonded headlamp. First, in the headlamp manufacturing process, the
headlamp is designed so that the lens can be clipped onto any
housing/reflector assembly and be assured of meeting the photometric
performance requirements of Standard 108 * * * [T]he design permits
only a positive and secure attachment. There are no shims or
adjustments that could influence the lens mounting. Second, from a
design point of view, the physical size of the reflector and lens
make the headlamp highly insensitive to minute positioning
variations in mounting and/or manufacture.
4. Vehicle Maintenance
All affected vehicles are within the time constraints of the
warranty period. Thus, within the next 12 months, [Mercedes] will be
able to remedy the noncompliance when the subject vehicles are
brought in for service. [Mercedes] will direct dealers to bond the
headlamps of all noncomplying vehicles brought to authorized dealers
for service.
5. Conclusion
In view of the fact that the headlamps comply with all
performance aspects of Standards 108, that the replacement lenses
are no longer available from (Mercedes) or its dealers, and that the
vehicles will be remedied shortly through routine warranty
maintenance, there is no adverse impact on safety. Therefore,
[Mercedes believes that] NHTSA should grant [its] petition for an
exemption for and inconsequential noncompliance with Standard 108.
Interested persons are invited to submit written data, views, and
arguments on the petition of Mercedes, described above.
Comments should refer to the docket number and be submitted to:
Docket Section, National Highway Traffic Safety Administration, room
5109, 400 Seventh Street, SW., Washington, DC 20590. It is requested
but not required that six copies be submitted.
All comments received before the close of business on the closing
date indicated below will be considered. The application and supporting
materials, and all comments received after the closing date, will also

petition is granted or denied, the notice will be published in the
