LR3/Disco 3
The rear lamp assembly is a one piece unit which contains a stop/tail lamp, a turn signal lamp, a second tail lamp, a
reversing lamp and a fog lamp. Five bayonet fitting bulbs are used (six on NAS vehicles with the addition of a side marker
lamp). These are located in holders which fit into the applicable hole in the lamp housing and are locked by rotating. Each
bulb holder is connected by wires to a connector on the rear of the lamp housing.
The rear lamp assembly is located in a recess in the vehicle body. Two studs on the outer edge of the lamp housing
locate in the vehicle body. The lamp is secured with two screws which are located on the inner edge of the lamp housing,
near the tailgate aperture.
Rear Stop and Side Lamp
The upper lamp is a combined stop and tail lamp and uses a 21W/5W bayonet fitting bulb. The stop lamp uses the 21W
bulb filament and the tail lamp uses the 5W bulb filament.
The stop lamp is activated when the ignition switch is in the ignition position (II) and the brake pedal switch is active (by
depressing the brake pedal). The high mounted stop lamp will also be activated when the brake pedal is pressed.
The stop lamps can also be activated by the ABS when Hill Descent Control (HDC) is active. A signal from the ABS
module energises a relay which supplies power to the stop lamps and high mounted stop lamp. For additional information,
refer to
Anti-Lock Control - Traction Control
(206-09A )
Turn Signal Lamp
The turn signal lamp is located below the combined stop/tail lamp and uses a 21W bayonet fitting bulb.
The turn signal lamps are operated by the left hand steering column multifunction switch or by the hazard flasher switch.
The steering column multifunction switch is only active with the ignition switch in the ignition position (II), the hazard
flasher switch is active at all times. When active, the turn signal lamps will flash at a frequency cycle of 380ms on and
380ms off.
If a bulb fails, the remaining turn signal lamp bulbs on that side of the vehicle flash at normal speed. The applicable turn
signal indicator in the instrument cluster will flash at double speed to alert the driver to the bulb failure.
Side Lamp
The side lamp is located below the turn signal indicator and uses a 21W/5W bayonet fitting bulb. Only the 5W filament is
used for the side lamp function.
The side lamps are operated by selecting side lamps or headlamps on the lighting control switch. The side lamps are
operational at all times and are not dependant on the ignition switch position. The side lamps will also be illuminated when
the lighting control switch is in the AUTO position and a 'lights on' signal is received by the CJB from the rain/light sensor.
Reversing Lamp
The reversing lamp is located below the tail lamp and uses a 21W bayonet fitting bulb.
The reverse lamp is active when the ignition switch is in the ignition position (II) and the CJB receives a reverse selected
signal on the CAN bus. Both manual and automatic transmissions have a reverse switch which senses when reverse is
selected.
Rear Fog Lamp
The rear fog lamp is located at the bottom of the rear lamp and uses a 21W bayonet fitting bulb.
The rear fog lamp is controlled by the lighting control switch. When the ignition switch is in the ignition position (II) and the
lighting control switch is in the side lamp or headlamp position, the lighting control switch can be pulled to the second
position (if front fog lamps fitted) to activate the front fog lamps. If front fog lamps are not fitted, the switch need only be
pulled to the first position. A rear fog lamp warning indicator is illuminated in the instrument cluster when the rear fog
