I. Background

    The National Highway Traffic Safety Administration (NHTSA) issued a 
Notice of Proposed Rulemaking (NPRM) in 1995 to address a petition from 
the Groupe de Travail Working Party ``Brussels 1952'' (GTB).\1\ The 
petitioner asked the agency to harmonize the U.S. visibility 
requirements with the United Nations Economic Commission for Europe 
(UNECE or ECE) requirements. As a result, the agency published a 
proposal that included several aspects of harmonization including 
visibility of reflex reflectors (front side, rear, rear side, 
intermediate), side markers (front, rear, intermediate), front turn, 
rear turn, stop, front parking, tail, rear fog, high mount stop, and 
daytime running lamps. In addition, the agency requested comments on 
allowing amber rear side markers and regulating front and rear fog 
lamps.
---------------------------------------------------------------------------

    \1\ See 60 FR 54833 October 26, 1995.
---------------------------------------------------------------------------

    In response to comments received, the agency followed the NPRM with 
a Supplementary Notice of Proposed Rulemaking (SNPRM) \2\ in 1998 that 
limited the scope to only visibility and terminated proposed rulemaking 
that would allow an option of providing amber rear side marker lamps 
and reflectors. The SNPRM proposed using either Society of Automotive 
Engineers (SAE) or ECE derived visibility requirements. In a separate 
notice, the issue of regulating front and rear fog lamps was also 
terminated.\3\
---------------------------------------------------------------------------

    \2\ See 63 FR 68233 December 10, 1998.
    \3\ See 62 FR 8883 February 27, 1997.
---------------------------------------------------------------------------

    In 2004, NHTSA published a final rule \4\ that was based on the 
UNECE derived visibility requirements. Regarding the method of 
certification, the final rule stated the visibility requirements could 
be satisfied by meeting a minimum visible area or by a minimum 
photometric intensity. The final rule set a compliance date of 
September 1, 2011 for vehicles that are less than 2032 mm in overall 
width, and September 1, 2014 for vehicles that are 2032 mm or more in 
overall width.\5\
---------------------------------------------------------------------------

    \4\ See 69 FR 48805 August 11, 2004.
    \5\ Dual dimension (80 in) has not been added because it does 
not appear in the regulation text S5.3.2(b) which is the primary 
area of interest for this background.
---------------------------------------------------------------------------

II. Petitions for Reconsideration

    Seven petitions for reconsideration were received from automotive 
manufacturers, lighting suppliers, and motorcycle manufacturers. 
Petitions for reconsideration were received from the Motor and 
Equipment Manufacturers Association (MEMA), the Alliance of Automobile 
Manufacturers (AAM), General Motors (GM), Sierra Products, North 
American Lighting (NAL), Harley Davidson, and the Motorcycle Industry 
Council (MIC). Among the seven petitions, six issues were raised that 
requested reconsideration of the final rule. In addition, there were 
also several requests, which could be characterized as clarifications, 
related to the final rule that did not specifically request a rule 
change. Finally, several general questions were received that are 
related to FMVSS No. 108 but which are not directly related to the 
final rule. These items are all summarized below.

1. Issue Regarding Harmonization of FMVSS No. 108 With ECE Regulation 
No. 53 (ECE R53) for Vehicles With Less Than 4 Wheels

    Two petitions for reconsideration were received regarding the 
visibility requirements of motorcycles from

[[Page 23507]]

Harley Davidson and MIC. Both of these petitioners supported the goal 
of standards harmonization, however they argued that the requirements 
in the final rule did not harmonize with the ECE R53 standard for 
motorcycles. Specifically, both petitioners stated that ECE R53 allows 
a narrower field of visibility for front and rear turn signal lamps, 
and for multiple lamp stop configurations on motorcycles. Additionally, 
both petitioners recommended decreasing the inboard visibility for 
motorcycle turn signal lamps from 45 degrees to 20 degrees. They also 
recommended decreasing the inboard visibility for multiple lamp stop 
configurations from 45 degrees to 10 degrees.

2. Issue Whether New Definition for the Effective Projected Luminous 
Lens Area Changes the Existing Requirements

    MEMA, AAM, and GM claimed that the new definition for the 
``effective luminous lens area'' would influence lamps designed before 
this final rule was effective. GM requested that the new definition not 
become mandatory until the new visibility requirements become mandatory 
on September 1, 2011, or September 1, 2014 depending on the width of 
the vehicle. AAM requested that the new definition for effective 
projected luminous lens area apply only to vehicles certified to the 
new visibility requirements. MEMA objected to what it believes was a 
lack of notice in changing the definition, as well as the lead time for 
compliance with the new definition. MEMA also objected to the exclusion 
of transparent lenses in the calculation of the effective projected 
luminous lens area.

3. The Lead Time for Wide Vehicles

    MEMA petitioned that the lead time be increased to at least 15 
years for wide vehicles. MEMA focused on two major points, the first 
being that NHTSA ``ignored the substantial cost this rule will impose 
on lighting suppliers in the heavy vehicle segment.'' MEMA also stated 
that ``the final rule provides no demonstrated safety benefits.''

4. Compliance Method Choice Is Irrevocable

    MEMA also petitioned that the manufacturer's choice of compliance 
method should not be irrevocable. MEMA stated that this will limit the 
selection of catalog lamps that a manufacturer can choose from in the 
event of an interruption in the supply of the originally certified 
lamp. MEMA also stated that the safety neutrality of the compliance 
method makes enforcement of this regulation impossible.

5. Requirements for Lamps Mounted Less Than 750 mm Above the Road 
Surface

    MEMA and NAL both petitioned that the photometric requirements of 
lamps mounted less than 750 mm above the roadway should be clarified. 
NAL pointed out that the preamble seems to include side marker and 
clearance lamps in the 750 mm rule, but the regulation text specifies 
signal lamps and reflective devices. NAL requested that the 
requirements for side marker and clearance lamps mounted less than 750 
mm above the road surface be made clear.

6. Requirements for Lamps Mounted 15 Above the Road Surface

    Sierra Products suggested that the agency further reduce the 
photometric requirements of lamps mounted 15 inches above the roadway, 
on the basis that a reduction in required light below Horizontal-
Vertical (H-V) could allow for a more economical lamp.

7. Additional Questions That Do Not Request a Rule Change, or Are Not 
Part of This Rulemaking

    Sierra Products asked several questions that do not request a 
specific rule change. In addition, Sierra Products also asked questions 
that are not part of this rulemaking. Among those questions, Sierra 
Products asked why the spacing, position, and color harmonization was 
abandoned. Also, Sierra Products asked for clarification as to the 
meaning of ``apparent surface'' as it was used in the preamble to the 
final rule. Among other clarification type questions, Sierra Products 
asked if large vehicle H-V area requirements changed as part of the 
final rule, and how the area compliance option will be tested for 
compliance. They also asked why big rigs and boat and utility trailers 
need reduced constraints on styling for aerodynamic purposes.
    Sierra Products asked several questions that are related to FMVSS 
No. 108, but are not part of this rulemaking. Those included a question 
about clearance lamp requirements. Sierra Products asked ``how can a 
big rig clearance light that is only effective at auto eye level be 
seen and understood by following, or passing auto traffic if it is 
allowed to be mounted 12 feet high and have no inboard photometric 
output?'' They also asked about the use of the latest SAE standards 
within FMVSS No. 108. In addition, Sierra Products asked for 
clarification as to the meaning of a multiple compartment lamp, and if 
a LED is considered a separate lamp. Continuing, Sierra Products asked 
``where have you discussed in this harmonization proposal that an 
advertised 100,000 hour LED doesn't hold up when its circuitry is 
heated or moistened, and who's responsible for the safety implications 
when a big rig or utility trailer $30 replacement LED brake or turn 
light can't be found anywhere?'' Finally, Sierra Products asked the 
status of other rulemakings unrelated to the final rule.

III. Discussion and Analysis

1. Issue Regarding Harmonization of FMVSS No. 108 With ECE Regulation 
No. 53 (ECE R53) for Vehicles With Less Than 4 Wheels

    The agency has considered the issue raised by Harley Davidson and 
MIC that the final rule failed to harmonize motorcycle lamp visibility 
with the ECE regulations. MIC stated that it believes the interests of 
harmonization will be better served by recognizing and harmonizing with 
the existing ECE regulations for motorcycle lighting. Harley Davidson 
stated that the agency's failure to incorporate ECE R53 within the 
final rule means that designs, standard and appropriate throughout the 
world, may not be able to be used in the U.S. NHTSA has evaluated the 
merits of this request in connection with harmonization and ensuring 
safety. In the final rule, we explained our general approach to 
harmonize the U.S. lamp visibility requirements with the ECE 
requirements and to increase the field of view of signal lamps.
    Specifically for motorcycles, prior to the compliance date 
specified by the August 2004 final rule, turn signals lamps are 
required to be visible through a horizontal angle starting at 0 degrees 
inboard (directly in front of the lamp) and continuing to 45 degrees 
outboard. The final rule added a vertical component to the field of 
visibility and increased the horizontal angle to 45 degrees inboard and 
45 degrees (area option) or 80 degrees (intensity option) outboard 
depending on the choice of visibility options. MIC's petition for 
reconsideration requested that, for motorcycles, the inboard horizontal 
angle match the requirements in ECE R53, which is 20 degrees inboard. 
NHTSA considers MIC's petition regarding motorcycle turn signal lamp 
visibility an improvement over the 2004 final rule as it better 
harmonizes these requirements with the well established safety standard 
used in various parts of the world without an expected decrease in 
safety.

[[Page 23508]]

    In addition, prior to the compliance date specified by the August 
2004 final rule, stop lamps mounted on motorcycles are required to be 
visible through a horizontal angle 45 degrees inboard to 45 degrees 
outboard. The 2004 rule added a vertical component to the required 
field of view. MIC requested that to further harmonize these motorcycle 
requirements with those of ECE R53, NHTSA should decrease the inboard 
angle requirement for a two stop lamp configuration. MIC noted that ECE 
R53 requires, for a two stop lamp configuration, that each lamp meet a 
horizontal visibility angle of 10 degrees inboard. Because the 
separation between stop lamps is typically small for motorcycles, NHTSA 
agrees that harmonizing the inboard visibility requirement is not 
expected to have a negative impact on safety.
    Accordingly, this notice adopts visibility requirements for 
motorcycle lamps based on the ECE R53 regulation.\6\ The standard is 
modified, establishing visibility requirements for motorcycles defined 
by the following corner points:
---------------------------------------------------------------------------

    \6\ ECE R53 Revision 2 ``Uniform Provisions Concerning the 
Approval of Category L3 Vehicles with Regard to the Installation of 
Lighting and Light Signaling Devices.''

Turn Signal............................  15 deg. UP-20 deg. IB..............  15 deg. UP-80 deg. OB.
                                         15 deg. DOWN-20 deg. IB............  15 deg. DOWN-80 deg. OB.
Stop...................................  15 deg. UP-45 deg. RIGHT...........  15 deg. UP-45 deg. LEFT.
                                         15 deg. DOWN-45 deg. RIGHT.........  15 deg. DOWN-45 deg. LEFT.
Tail...................................  15 deg. UP-80 deg. RIGHT...........  15 deg. UP-80 deg. LEFT.
                                         15 deg. DOWN-80 deg. RIGHT.........  15 deg. DOWN-80 deg. LEFT.


    Two footnotes are added to both Table V-b and Table V-c as follows:

    If a multiple lamp arrangement is used for a motorcycle stop 
lamp, the inboard angle for each lamp shall be 10 degrees.
    If a multiple lamp arrangement is used for a motorcycle tail 
lamp, the inboard angle for each lamp shall be 45 degrees.

2. Issue Whether New Definition for the Effective Projected Luminous 
Lens Area Changes the Existing Requirements

    MEMA, AAM, and GM claimed that a modified definition for the 
effective projected luminous lens area changed requirements that were 
not intended to be changed in the final rule, and petitioned for relief 
by either a longer lead time, that the definition only apply to 
vehicles certified to the new visibility requirements, or that the 
definition be reverted back to its original form. The agency does not 
agree with the petitioners, nor the suggestions for relief. Instead, we 
believe that the definition published in the final rule only clarified 
the definition and that the definition itself did not establish any new 
requirements.
    The definition prior to the final rule stated: ``Effective 
projected luminous lens area means the area of the projection on a 
plane perpendicular to the lamp axis of the portion of the light-
emitting surface that directs light to the photometric test pattern, 
and does not include mounting hole bosses, reflex reflector area, beads 
or rims that may glow or produce small areas of increased intensity as 
a result of uncontrolled light from small areas (\1/2\ deg. Radius 
around the test point).''
    The final rule separated this definition into two parts to more 
specifically define the meaning of the light-emitting surface. It reads 
as follows:
    ``Effective light-emitting surface means that portion of a lamp 
that directs light to the photometric test pattern, and does not 
include transparent lenses, mounting hole bosses, reflex reflector 
area, beads or rims that may glow or produce small areas of increased 
intensity as a result of uncontrolled light from an area of \1/2\ 
degree radius around a test point.''
    ``Effective projected luminous lens area means the area of the 
orthogonal projection of the effective light-emitting surface of a lamp 
on a plane perpendicular to a defined direction relative to the axis of 
reference. Unless otherwise specified, the direction is coincident with 
the axis of reference.''
    This definition clarification has two major aspects. First it 
clarifies that ``projection on a plane'' means an orthogonal 
projection. This clarifies, but does not change, the previous 
definition. The final rule stated that ``we believe these two phrases 
have the same meaning * * * the term orthogonal projection has greater 
clarity.'' \7\ The second aspect is the addition of the words ``and 
does not include transparent lenses.'' This exclusion of transparent 
lenses is not new with this definition as it reflects a previous agency 
interpretation letter to Mr. Shigeyoshi Aihara on June 14, 2000.\8\ As 
explained in this interpretation letter, transparent lenses are 
excluded because they do not direct light, they simply allow light to 
pass through them freely. Similarly, the dictionary defines transparent 
as ``having the property of transmitting light without appreciable 
scattering * * *'' \9\ In consideration of these factors, the agency 
believes that no significant change in the method by which the 
effective luminous lens area is calculated has been made by this final 
rule. As such, there is no reason to delay the effective date as 
requested by GM, nor to apply this clarified definition only to 
vehicles certified to the new visibility requirements of the final 
rule. Likewise, the agency does not agree that a lack of notice was 
provided. As such, the agency is denying the requests from MEMA, AAM, 
and GM.

---------------------------------------------------------------------------

3. The Lead Time for Wide Vehicles

    MEMA petitioned to adopt a lead time of 15 years for wide vehicles 
because it believes that NHTSA underestimated the costs. The agency 
disagrees. The final rule permitted an alternative method of compliance 
until September 1, 2011 for vehicles less than 2032 mm in overall 
width, or until September 1, 2014 for vehicles of 2032 mm or more in 
width. Effectively, this provided the wider vehicles a lead time of 10 
years, and 7 years for the more narrow vehicles. The agency believes 
that the lead time provided is adequate and notes that no new data was 
submitted indicating manufacturing costs, design constraints, or other 
information that the agency could evaluate. Similarly, the agency notes 
that unanticipated design changes would likely be limited to the lamps 
only, not to the entire vehicle, as was described in the final 
rule.\10\ In consideration of these factors, the agency is denying this 
request.
---------------------------------------------------------------------------

    \10\ See 69 FR 48811 August 11, 2004.
---------------------------------------------------------------------------

4. Compliance Method Choice Is Irrevocable

    MEMA also requested that the agency eliminate the irrevocable 
choice of compliance wording from the final rule because it limits the 
selection of catalog lamps from which a manufacturer can choose. This 
issue was addressed in the

[[Page 23509]]

comments based on the SNPRM, and the agency decided to carry the 
wording from the SNPRM into the final rule. The preamble to the final 
rule states:
    ``We continue to believe that when a vehicle manufacturer has 
certified that the vehicle will meet a visibility requirement with a 
lamp installed and tested according to a chosen compliance method, the 
method chosen should be used to determine compliance of that vehicle 
with the visibility requirements applicable to that lamp. This 
provision is needed for the agency to effectively carry out its 
enforcement responsibilities. The agency wants to avoid the situation 
of a manufacturer confronted with an apparent noncompliance (based on a 
compliance test) with the option it has selected responding to that 
noncompliance by maintaining that its products comply with a different 
option for which the agency has not conducted a compliance test. To 
ensure that the agency will not be asked to conduct multiple compliance 
tests, first for one compliance option, then for another. This rule 
requires the vehicle manufacturer to select the option by the time it 
certifies the vehicle and prohibits it from thereafter selecting a 
different option.'' \11\
---------------------------------------------------------------------------

    \11\ See 69 FR 48810 August 11, 2004.
---------------------------------------------------------------------------

    We note that vehicle manufacturers certify each vehicle to the 
Federal motor vehicle safety standards. In the case of a standard with 
compliance options, the manufacturer is not required to select the same 
compliance option for similar or even identical vehicles, so long as 
the vehicle being certified complies with the option selected by the 
manufacturer. Thus, the requirement that a vehicle manufacturer select 
a particular compliance option by the time it certifies a vehicle does 
not limit manufacturer design choices.
    Therefore, the agency is denying this request.

5. Requirements for Lamps Mounted Less Than 750 mm Above the Road 
Surface

    MEMA and NAL petitioned the agency to clarify the requirements for 
lamps mounted less than 750 mm above the road surface. The agency 
believes that this ambiguity was resolved in the FMVSS No. 108 
administrative rewrite final rule.\12\ That final rule contains 
footnotes within the photometric requirements (Table VI a and b, Table 
VII, Table VIII, Table IX, Table X, Table XI, Table XIII a and b, Table 
XIV, and Table XVI a) that explicitly state the ``photometry 
requirements below 5[deg] down may be met at 5[deg] down rather than at 
the specified required downward angle.'' Likewise, it also contains 
similar footnotes within Tables V-b and V-c. Therefore, we believe this 
request has already been addressed and requires no further action.
---------------------------------------------------------------------------

    \12\ See 72 FR 68234 December 4, 2007.
---------------------------------------------------------------------------

6. Requirements for Lamps Mounted 15 Inches Above the Road Surface

    Sierra Products petitioned the agency to eliminate the downward 
photometric requirements for lamps mounted 15 inches above the road 
surface. However, the petitioner did not provide any evidence 
demonstrating that safety would not be compromised, particularly on 
uneven roadways. The agency notes that the allowance for lamps mounted 
less than 750 mm above the road surface was created in order to 
harmonize FMVSS No. 108 visibility requirements with the ECE visibility 
requirements. The petitioner does not cite, nor does the agency know 
of, any allowance for lamps mounted 15 inches above the road surface 
within the ECE regulation. As such, the agency is denying this request.

7. Additional Questions That Do Not Request a Rule Change, or Are Not 
Part of This Rulemaking

    Sierra Products raised several questions that demonstrated a 
request for clarification. These questions do not request a rule 
change, and some are not related to this rulemaking. These questions 
are addressed below.
    Sierra Products asked what happened to the proposed harmonization 
of side marker lamps. The original NPRM did propose allowing rear side 
markers to be amber in color. This rulemaking proposal was terminated 
in the SNPRM.13 14 The reasons cited for the termination 
included major differences in the side marker requirements between the 
U.S. and European regulations, and the lack of data indicating whether 
it is important for the drivers to know which end of the vehicle is 
about to merge into their path.
---------------------------------------------------------------------------

    \13\ See 60 FR 54833 October 26, 1995.
    \14\ See 63 FR 68233 December 10, 1998.
---------------------------------------------------------------------------

    Sierra Products also asked what is meant by the term ``apparent 
surface'' as used in the preamble to the final rule. The term 
``apparent surface'' does not appear in the regulations of FMVSS No. 
108. However, it does appear in the discussion ``How the ECE Visibility 
Requirements Differ from the Current Requirements of FMVSS No. 108'' of 
the final rule preamble. This term is a well defined term in ECE No. 
48. That document states that ``the apparent surface for a defined 
direction of observation means, at the request of the manufacturer or 
his duly accredited representative, the orthogonal projection of: 
Either the boundary of the illuminating surface projected on the 
exterior surface of the lens or the light-emitting surface.'' The 
precise definition is only in reference to an ECE regulation, and is 
not required in the discussion of this rule, nor will it be used to 
determine compliance with FMVSS No. 108.
    Regarding Sierra Products' statement that they could not tell if 
the H-V area requirement was changed for wide vehicles, we note that no 
effective projected luminous lens area requirements projected in 
coincidence to the axis of reference were changed with this rulemaking.
    Sierra Products asked how NHTSA would check the compliance of the 
effective projected luminous lens area requirements. We note that 
NHTSA's Office of Vehicle Safety Compliance (OVSC) provides contractor 
laboratories with Laboratory Test Procedures as guidelines for 
obtaining compliance test data. The data is used to determine if a 
specific vehicle or item of motor vehicle equipment is potentially non-
compliant with an applicable FMVSS. The Laboratory Test Procedure for 
FMVSS No. 108 is available on NHTSA's Web site.\15\ It should be noted 
that the OVSC Laboratory Test Procedures, prepared for the limited 
purpose of use by independent laboratories under contract to conduct 
compliance tests for the OVSC, are not rules, regulations or NHTSA 
interpretations regarding the meaning of a FMVSS, and are not intended 
to limit the requirements of the applicable FMVSS(s).
---------------------------------------------------------------------------

    \15\ Available at http://www.nhtsa.gov/DOT/TP-108-13.pdf.
---------------------------------------------------------------------------

    Finally, Sierra Products inquired as to the status of rulemaking 
that was not part of this rule. Harmonization rules such as ``bulb 
design, bulb tolerance, weathering, non required lamps, clearance 
lamps, life span, markings, and replacement light sources'' will go 
through the rulemaking process, as appropriate. The remaining 
statements and questions proposed by Sierra Products either are not 
related to the final rule, or do not request a specific rule change.

IV. Effective Dates and Compliance Dates

    As noted earlier, the August 2004 final rule set a compliance date 
of September 1, 2011 for vehicles that are less than 2032 mm in overall 
width, and September 1, 2014 for vehicles that are 2032 mm or more in 
overall width.

[[Page 23510]]

Those compliance dates are not changed by today's rule. There are two 
effective dates for the amendments we are adopting, one for the current 
version of FMVSS No. 108 and the second for the FMVSS No. 108 
administrative rewrite final rule.

V. Conclusion

    For the reasons discussed above, we are granting the requests to 
make certain changes pertaining to the visibility of lamps mounted on 
motorcycles to increase the compatability of our visibility 
requirements with those of the United Nations Economic Commission for 
Europe (UNECER53), and we are otherwise denying the petitions.

VI. Rulemaking Analyses and Notices
