Bi-xenon headlamps
Details & Technology
The bi-xenon headlamps use xenon lighting technology to produce both the low and high-
beam lights.
The light source is a gas HID (High Intensity Discharge) lamp which produces a luminous arc
in a quartz bulb filled with a gas mixture. The same gas discharge bulb is used for both the
low and the high-beam lighting.
With bi-xenon headlamps, LED daytime driving lamps are included. The LED daytime
driving lamps will be switched on independently of the master light switch position with
engine start. In this case further lights are not active. The LED daytime driving lamps dim
down with the use of the low beam light. The daytime driving lamps can be switched
permanently on/off at the instrument cluster or by the optionally available multifunction
steering wheel, code CL4.
The high beam is produced using the full light beam, while the low beam is produced by
moving a shutter between the bulb and the lens, so that the long-range portion of the light is
blocked off, thus preventing blinding oncoming traffic.
Sensor-controlled dynamic range adjustment automatically counteracts changes in the
angle of the headlamps caused by changes in the attitude of the vehicle when braking or
accelerating, or due to changes in payload, and prevents blinding for oncoming drivers.
If the windscreen washer is operated when the headlamps are switched on, water jet nozzles
are automatically extended and the headlamps are cleaned with a high-pressure jet.
Benefits & Arguments
• Significantly increased range in low-beam mode
• Wider illumination of the road perimeter in low-beam mode
• Long service life
• Automatic headlamp range adjustment prevents oncoming traffic from being blinded
Remarks
Vehicles with bi-xenon headlamps are fitted with automatic headlamp range adjustment and a
headlamp cleaning system.
