It lives in a hot, dirty spot, and after 30-plus years the contacts wear or the plunger sticks. Common symptoms include reverse lights that never come on, lights that come on only sometimes or only after a few tries, lights that stay on all the time, or a reverse light fuse that keeps blowing because of a shorted switch. Working reverse lights are required for inspection in many states, and they help other drivers see you backing up. If the bulbs, fuse and wiring check out, this inexpensive switch is the usual cause. Testing is easy: unplug the two wires, bridge them, and if the lights come on with the ignition on, the switch is bad.\u003c\/p\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRaise the car safely on stands.
