Headlamp: Description and Operation

The headlamp system consists of the following components:
^ Two headlamps.
^ Lamp switch.
^ Relays for switching 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 (CJB) 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 "high 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 BJB.
