Frequently asked questions

What does the reverse light switch do?
The reverse light switch threads into the manual gearbox casing and closes the reversing-lamp circuit when reverse gear is selected, illuminating the reverse lights. It's fitted with a two-pin connector and works as a simple on/off contact triggered by the selector.
What are the signs the reverse light switch has failed?
A failed reverse light switch typically leaves the reverse lights off when reverse is selected, or occasionally stuck on. Wiring, connector, and bulbs are worth checking first, since those faults can mimic a failed switch before you replace it.
How is the reverse light switch fitted?
The reverse light switch screws into the gearbox casing and is fitted with a spanner or socket, then the two-pin connector clips on. It's usually a straightforward DIY job. Check the gearbox oil level afterwards, as a little oil can weep from the port during the swap.
