Headlamp: Description and Operation

The headlamp system consists of:
^ two headlamps,
^ light switch,
^ Relay for switching between main and dipped beam,
^ direction indicator/dipped beam switch,
^ main beam display,
^ wiring,
^ fuses,
^ headlamp levelling system.

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

When the headlamps are switched on, a voltage is supplied to the main beam/dipped beam switch and to the dipped beam relay. The relay for the dipped beam is located in the Battery Junction Box (BJB) in the engine compartment.

If the main beam/dipped beam switch is set to "dipped beam", then a voltage is supplied via the dipped beam relay to the dipped beam part of the headlamp assembly. The left and right-hand dipped beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.

If the main beam/dipped beam switch is set to "main beam", then a voltage is supplied via the main beam relay to the main beam part of the headlamp assembly. The left and right-hand main beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.
