What is Reversing Light Switch?

It screws into the gearbox casing. Automatics use the range sensor instead. It may also activate the reversing camera. Testing is simple: check continuity across the switch with reverse selected and not selected.

How it works

The reverse selector pushes the switch plunger.

Why it matters for your car

A faulty switch leaves reversing lights off. Oil leaks can occur at its seal.
