LIGHTING

86-2-16 DESCRIPTION AND OPERATION

The Bi-xenon headlamps use a complex surface reflector for the halogen fill in main beam only lighting unit, as used 
on the halogen headlamp. This type of reflector is divided into separate parabolic segments, with each segment 
having a different focal length. 

The main beam bulbs are quartz halogen, with a rating of 55W. The bulbs are retained in the headlamp unit with 
conventional wire retaining clips.

The bi-xenon headlamps operate as a dip beam and a main beam headlamp unit. The xenon lamp comprises a 
projector lens with a solenoid controlled shutter to change the beam output from dip to main beam.

NOTE: Bi-xenon lamps do not operate when the main beam 'flash' function is operated.

The bi-xenon headlamp system is controlled by the LCM using a control module and igniter located on each headlamp 
to operate the xenon bulb. The control modules and igniters provide the regulated power supply required to illuminate 
the xenon bulbs through their start-up phases of operation.

Safety Precautions

WARNING: The xenon system generates up to 28000 volts and contact with this voltage could lead to fatality. 
Make sure the headlamps are switched off before working on the system.

The following safety precautions must be followed when working on the xenon headlamp system:

l

DO NOT attempt any procedures on the xenon headlamps when the lights are switched on

l

Handling of the DS2 xenon bulb must be performed using suitable protective equipment, e.g. gloves and goggles. 
The glass part of the bulb must not be touched

l

Xenon bulbs must disposed of as hazardous waste

l

Only operate the lamp in a mounted condition in the reflector.
