How do you check a reversing light on a car?
If the lights were added after the car was made, the switch may be a manually operated one mounted on the dash. To check the reverse switch is working correctly, turn the ignition on and select reverse gear. Connect one side of the test lamp to earth and probe each terminal in turn. The switch should illuminate when each terminal is touched.
Why does my reversing light only light on one terminal?
If the lamp lights on both terminals, the fault is in the wiring between the switch and reversing lights. If the lamp fails to light at all, check the wiring between the fuse and switch. If the lamp only lights on one terminal, the switch is either broken or needs adjusting.

Why are the reverse lights on my Mercedes not working?
Although my car is a 2000 W202 wagon, this would pertain to most Benz late 90’s with automatic transmission. The reverse lights started acting up a few months ago – I could get them to come on only by teasing the gear selector. After a few months of that, they stopped working altogether.
What happens when two reversing lights go together?
If the bulb still fails to light, the fuse may have blown. You should also suspect a blown fuse if two reversing lights go together. In many cases the fuse protecting the reversing lights also covers other accessories (see your car handbook to find out which ones).
Is there a fuse under the hood for the reverse lights?
This is what I’ve found while trying to troubleshoot this problem, maybe someone can help me. 1) The fuse under the hood for the reverse lights is good and had power across it while the gear select lever is in Park and Reverse, but no other gears. 2) I do hear a relay snapping on/off in the dash somewhere when I remove and reinstall the fuse.
