If the lights were added after the car was made, the switch may be a manually operated one mounted on the dash.

The switch should illuminate when each terminal is touched.

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.

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.
