Interior Lighting Introduction

Locations:

Glovebox lamp
The glovebox lamp operates whenever the glovebox door is opened. The lamp comprises a combined switch and bulb holder assembly. The bulb aperture in the glovebox is covered by a white lens

Door guard/puddle lamps
A door guard/puddle lamp, fitted to the rear lower corner of each door, operates automatically whenever the corresponding door is opened. Each lamp assembly has a double lens; red to project rearwards to warn oncoming traffic that the door is open and white to illuminate the passenger 'step-out' area.

Front courtesy/map lamps
The roof console comprises a module with integral switches which permits operation of the driver and front passenger courtesy and map lamps.

Where appropriate, the module also controls operation of the sun roof and garage door opener.

Rear courtesy/reading lamps
Each rear quarter of the passenger compartment is fitted with combined lighting units comprising; a rear courtesy lamp and reading lamp. The courtesy lamps operate automatically whenever a rear door is opened; the reading lamps function when the integral switches are operated by occupants of the vehicle.

Trunk lamps
The trunk trim panel is fitted with lamps which operate automatically whenever the trunk lid is opened; the switch is incorporated within the latch mechanism.

Vanity mirror lamps
The vanity mirror lamps, two on each sun visor, operate automatically when the mirror flap is opened, provided the sun visor spindle is engaged in the stowage clip.

Operation
The BPM provides an enable signal for the glovebox, vanity mirror, trunk lid and map lamps. Actuation of the relevant switch provides an earth path to the lamp.

The rear passenger reading lamps receive a supply direct from fuse F10 in the RH heelboard fuse-box.

The front and rear courtesy lamps have separate fade functions controlled by the BPM.

The door hazard/puddle lamps are controlled locally by the relevant Door Module.
