The reversing lights are white lights fitted to the rear of a vehicle. They provide the driver with vision behind the vehicle at night, and also alert other drivers to the fact that the vehicle is to be reversed.
The circuit consists of:
When the ignition switch is on and the vehicle is placed in reverse gear current flows from the battery, through the ignition switch, to the closed reversing light switch on the transmission.
Electrical current flows across the closed switch to the reversing lights, and then returns to the battery by the earth return system.
