Xenon headlight, dipped beam 3
Xenon headlights produce roughly two times as much light as halo-
gen bulbs and have a significantly longer service life.
The lamp units consist of a gas discharge lamp containing xenon.
When the lights are switched on a very high voltage activates the
xenon gas. The lamps soon reach full intensity.
Cars with xenon headlights have automatic levelling. The levelling
system is comprised of two sensors, one on the front suspension
and one on the rear suspension, and a control unit by the engine bay
fuse box. Headlight alignment is adjusted automatically to the car’s
load to prevent dazzling drivers in oncoming traffic.
If a fault is detected in the system, the following message will be dis-
played on the SID:
WARNING
Xenon headlights are high tension. All work on xenon headlights,
including changing bulbs, must be carried out by dealer person-
nel.

We recommend you to contact a Saab
