ELECTRICAL SYSTEM
The trailer is equipped with a 24 V dc electrical system, which receives its power from the towing vehicle
through the trailer intervehicular cable assembly. The intervehicular cable assembly is connected to the
trailer chassis wiring harness, which leads to the two composite lights located at the rear of the trailer and to
the five running lights located at the sides and rear of the trailer.
Each composite light contains two lamps and two LEDs: one lamp functions as a taillight when the service
lights are turned on, one lamp functions as both a stoplight and turn signal, one LED functions as a
blackout taillight when the blackout light switch is turned on, and one LED functions as a blackout
stoplight when the blackout light switch is turned on. The blackout lights automatically turn off the taillight,
stoplight, and turn signals if both switches are on at the same time.
