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, a high-mounted
stoplight will illuminate simultaneously with the
stoplights on the sides for increased safety.
The stop and tail lights are combined in the
same 6-LED lamp. The directional signal and
license plate lights consist of individual LED
lights mounted on the engine rear door, and
each light is serviced individually as a complete
unit. The back-up light sealed unit uses a regular
tungsten bulb.
The hazard warning flashing system uses the
front, side and rear
simultaneously. This system is energized by a
switch on the L.H. dashboard.
