(b) Light locations
Added lights must be installed to assure vehicle compliance with the
requirements of FMVSS 108. If any light is hidden by the body or
other structure after the vehicle is completed, a component(s)
conforming to FMVSS 108 must be installed. Refer to FMVSS 108
for installation location.
(c) Light operation
In general vehicles, the tail, license, clearance, identification, and
side marker lights should illuminate when the headlight switch is set
to the first position.
In vehicles with a clearance light switch (special specifications), the
tail and license lights illuminate when the headlight switch is set to
the first position; the clearance light switch illuminates the clearance,
identification and marker lights. Lights of the same type in the front
and rear should illuminate at the same time.
(2) Installation of Lights supplied with Incomplete vehicle
(a) The rear combination light is temporarily installed on the rear of the
frame. The rear reflex reflector is built in the existing rear
combination light. Properly mount the light to assure compliance
with the requirements of FMVSS 108. The rear combination lights
can be installed in two ways, i.e., by using either the upper portion
or the front of each bracket. If possible, installation using the front
of the bracket is recommended in order to mount the lights as high
as possible. With either installation method, check for light vibration
during vehicle operation. If vibration is noted, add bracing from lower
edge of bracket to the underbody as shown in Fig. A.
• Installation using front fitting holes
Tighten the light bracket with 0.31 in (8 mm) diameter hexagonal
bolts and nuts at 3 places. Be sure to use plain washers. When
installing the light to the steel plate, they should be fixed not to
vibrate. The thickness of the plate is recommended to be more
than 0.13 in (3.2 mm).
