LR3/Disco 3
The row 1 and 2 interior lamp assemblies are common to all models, however, their location can differ between model
specification. Both lamp assemblies have three switches; one for the main interior lamp and two for the map reading
lamps.
On low line specification vehicles, the interior lamps are located directly into apertures in the headlining with a bezel finish
surround.
On high line specification vehicles, the row 1 (front) interior lamp is located in a housing which can also contain the
sunroof switch and/or the voice activation microphones, depending on specification. The row 2 (rear) interior lamp is also
located in a housing which contains the rear heating controls.
The main interior lamps operate as part of the automatic interior lighting system. The map reading lamps only operate
manually.
Both the interior and map reading lamps use 5W capless bulbs.
The row 1 interior lamp unit also contains an LED for the waterfall lighting. Waterfall lighting is part of the lighting control
switch functionality which also controls the brightness of the switch and instrument cluster display illumination. Waterfall
lighting provides very limited illumination for the center of the fascia and the center console, when the vehicle is being
driven, without affecting the driver's night vision.
Main Interior Lamp
The main interior lamps operate independently of the ignition switch position and can be operated automatically by one of
a number of inputs to the CJB or manually by pressing the central switch on the lamp assembly. The switch is a
momentary switch which is connected directly to and completes a circuit to the CJB. This completed circuit is a signal for
the CJB to activate or deactivate the row 1 interior lamp (and also the row 2 interior lamp, if fitted). The lamps will remain
on until the switch is pressed a second time.
The interior lamps can be permanently switched off as previously described by pressing and holding the central switch for
at least 3 seconds. The 3 second completion of the circuit is sensed by the CJB which grants the permanent off request.
Map Reading Lamps
Both row 1 and 2 interior lamp assemblies contain map reading lamps which are located adjacent to the main interior
lamp. The lamps are operated by two momentary switches on the lamp unit, which are located on either side of the main
interior lamp switch.
ROW 3 MAP READING LAMPS
The row 3 map reading lamps are located in the headlining, above the rear side windows. These map reading lamps are
only fitted to vehicles fitted with the seven seat, third row seating option.
The lamps operate independently of the ignition switch position. The lamps have a latching rocker switch which allows the
lamps to be manually switched on and off. The map reading lamps have a non-adjustable beam.
The lamps are not part of the automatic interior lighting system and therefore can only be switched on manually.
The map reading lamps use 5W capless bulbs.
