The brake lamps illuminate when the ignition is in position "II" and the brake pedal is depressed. The reverse lamps illuminate when the ignition is in position "II" and reverse gear is selected.
Operation
Feed from the positive battery terminal is connected to the engine compartment fuse box (C632-1) by a brown wire. Current passes through fusible link 2 (C907-2) and is connected to the ignition switch (C028-1) by a brown wire. When the ignition switch is in position "II", power flows across the switch (C094-1) and is connected to fuse 17 of the passenger compartment fuse box (C580-33) by a white wire. Current flows across the fuse (C580-34) and feeds the brake pedal switch (C075-1) and the reverse lamp switch (C167-2), which are connected in parallel. Both switches are fed by green wires.
Brake Lamps
When the brake pedal is depressed, the brake pedal switch closes and power flows through the switch. The brake pedal switch (C029-1) is connected to the LH tail lamp (C404-2), the trailer pick-up (C416-1), and the RH tail lamp (C401-2) by green/purple wires. All brake lamps are earthed on black wires.
Reverse Lamps
When reverse gear is selected, the reverse lamp switch is closed. Current flows across the reverse lamp switch (C167-1) to the RH reverse lamp (C455-2), and the LH reverse lamp (C490-1) on green/brown wires. Both reverse lamps are earthed on black wires.
