The back-up light switch closes the circuit to the reverse lamps when the vehicle is shifted into reverse. The lights then signal drivers and pedestrians behind you and help light the area as you back up.
Signs this part may need replacing: reverse lights that don't come on when you shift into reverse, lights that work only intermittently, or lights that stay on after you shift out of reverse. Bulbs, fuses, and wiring can cause the same symptoms, so diagnose the circuit before replacing the switch. If a failed switch is the cause, LS418 replaces it on the listed vehicles.
