Tail Lamp: Description and Operation

The rear tail lamp modules are mounted on the truck bed, outboard of the tailgate, and molded into the lines of the vehicle. Each module contains two bulbs, a lens, and a housing. One bulb is a two filament bulb used for tail, stop, and turn signal functions. The other bulb is a single filament bulb used for back-up light illumination.

Each tail lamp module can be serviced separately. Each bulb can also be serviced separately. The headlamp switch controls tail lamp operation. The multifunction switch controls turn signal operation, and the back-up light switch controls the back-up light operation. The brake lamp switch controls the stop lamp function.
