Tail Lamp: Description and Operation

Battery voltage is applied at all times to the coil and contacts of the tail lamp relay. With the light switch in PARK or HEAD, the coil of the tail lamp relay is grounded through the light switch. Battery voltage from the Left/Right tail lamp fuse is then provided to the lamps (Left/Right tail lamps, Left/Right park lamps and license lamp) through the tail lamp relay contact, and all the lamps illuminate.
