AND HAZARD WARNING LIGHTS
A combination stoplight, taillight, directional
signal light and back-up light assembly is
mounted at the rear, on each side of the vehicle.
Furthermore, when braking, two center
stoplights (LED) and a center high-mounted stop
light (CHSL) (LED) will illuminate simultaneously
with the stoplights on the sides for increased
safety. The L.H. and R.H. side center stop lights
are also used as directional signal and marker
lights.
The stop, tail, directional signal and back-up
lights consist of individual lamps, each equipped
with 6 LED lights, mounted together as a
module.
LED lights are not replaceable and each lamp is
serviced individually as a complete unit.
The hazard warning flashing system uses the
