Xenon headlight, low beam 3
Xenon headlights produce roughly two
times as much light as halogen 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 automati-
cally to the car’s load to prevent dazzling
drivers in oncoming traffic.
If a fault is detected in the system, the fol-
lowing message will be displayed on the
SID:
WARNING
Xenon headlights are high tension. All
work on xenon headlights, including
changing bulbs, must be carried out by
dealer personnel.
Headlight levelling
malfunction.
We recommend you to contact a Saab
dealer to have a xenon headlight changed
