Trailer Lamps: Description and Operation
Exterior Lighting
The headlamp switch is a four position switch that controls the headlamps, exterior lamps, panel lamps, and, if equipped, the fog lamps and the autolamp
system.
The autolamp system provides light sensitive automatic on-off control of the exterior lamps normally controlled by the regular headlamp switch. The
autolamp system keeps the lamps on for a preselected period of time after the ignition switch is turned off. The preselected time lapse is adjustable up to
approximately three minutes.
The multi-function switch controls the turn signals, high beams, and hazard lamps. The Brake Pedal Position (BPP) switch controls the brake lamps and
rear hi-mount lamp.
