Headlamp: Description and Operation

The headlamp system consists of:
^ Two headlamps.
^ Lamp switch.
^ Relay for switching between high and low beam.
^ Turn signal/high-low beam switch.
^ High beam display.
^ Wiring.
^ Fuses.

The voltage is supplied to the lamp switch through a fuse. This fuse is located in the central junction box in the left-hand footwell.

If the lamp switch is set to 'headlamps', a voltage is supplied to the low beam relay. The relay for the dipped beam is located in the Battery Junction Box (BJB) in the engine compartment.

If the high beam/low beam switch is set to 'main beam', then a voltage is supplied through the high beam relay to the high beam part of the headlamp assembly. The left and right-hand high beams are fused separately. The fuses are located in the Battery Junction Box (BJB) in the engine compartment.
