Reverse Light Switch for Gearbox – dependable back‑up lamp control
Keep your car safe and visible when reversing. This gearbox-mounted reverse light switch sends a clear signal to the rear lamps the moment you select “R”. It’s a small part with a big role: alerting pedestrians, guiding night-time parking, and complying with road safety rules. Built to factory specs for proper thread fit and plunger travel, it seals against oil leaks and survives heat, vibration, and gear oil exposure.
Why you need it
Without a reliable switch, your back-up lamps won’t turn on automatically. That means reduced rear visibility, higher risk in tight spaces, and potential inspection failures.
How it works
When you engage reverse, the transmission’s selector rail presses the switch plunger. Inside, contacts close, completing a 12V circuit to the tail lamps. Release reverse and the spring opens the circuit. Simple, robust, and instant.
If it fails ⚠️
Common signs: no reverse lights, lights stuck on, intermittent flicker, or gear oil seep at the switch body. Ignoring it can drain the battery (stuck on), invite tickets, and mask obstacles behind you. Replacement is quick: unplug, unthread, swap crush washer, torque, reconnect.
