DESCRIPTION

General
The headlamp assemblies each contain a side lamp bulb and a dual filament headlamp bulb. The tail lamps and rear number plate lamp operate together with the side lamps and headlamps, and share a dual filament bulb with the brake lamps. The rear number plate lamp is incorporated into the tail door handle.

The side and headlamps are controlled via the lighting switch, which is mounted on the end of the LH column switch. Turning the switch to its first position will illuminate the side lamps. Turning the switch to its second position will illuminate the headlamps. The headlamps can be switched between full and dipped beam by pulling the column switch back against (and past) spring pressure. When the headlamps are switched on, a blue warning lamp illuminates within the instrument pack.

If the side or headlamps are switched on, the ignition is switched off, and the driver door is opened, the Central Control Unit (CCU) will sound a 2 KHz sounder. The sounder is integral within the CCU, and informs the driver the lights have been left on inadvertently.

Headlamp Levelling
To prevent dazzling oncoming road users, the headlamps can be adjusted to compensate for the effect of different load on headlamp vertical alignment. Headlamp levelling is controlled via a four position switch mounted below the instrument pack. The switch operates a levelling motor on each headlamp when the lighting switch is in either the side or headlamp position.

The switch is marked with four positions, which should be used under the following conditions:
^ 0 - Driver, or driver and front seat passenger only (no luggage).
^ 1 - Driver and three passengers (no luggage).
^ 2 - Driver, three passengers and full luggage compartment.
^ 3 - Driver only, full luggage compartment.

NOTE: Headlamp levelling is not fitted to NAS vehicles
