Reverse Light Switch AMR3918 for R380 Gearbox

The Reverse Light Switch AMR3918 is the essential solution for restoring proper reverse-light operation on Land Rover models equipped with the R380 manual gearbox. Installed on the side of the R380 transmission housing, this switch activates the reverse lights when the selector engages reverse gear.

Over time, wear to the internal plunger or switch body can prevent proper electrical contact, resulting in inoperative reverse lights. This replacement switch is precision-engineered to match the original switching action and durability and has been tested under real off-road conditions by the Lucky8 team to ensure reliable operation.

This switch replaces part number AMR3918 and is ideal for addressing intermittent or failed reverse light operation caused by a worn or faulty transmission switch.
