Xenon lamps illuminate the side and 
front areas of the vehicle with signifi-
cantly more brightness and uniformity 
than traditional halogen lamps. 

In a xenon lamp, an electric arc 
replaces the filament to generate 
intense illumination. A gas mixture in a 
quartz glass tube with metal vapor is 
ignited by a high electric voltage. The 
arc that is generated is then sustained 
by a lower voltage. When the lamp is 
turned on, there is a brief warm-up 
period. Maximum brightness is attained 
in approx. 15 seconds.

Xenon lamps provide significantly 
improved visibility, especially during 
adverse weather conditions and driving 
situations (driving at night in heavy rain 
or through road repair areas where 
there are no lane markers, for instance). 

Vehicles with xenon lamps

are 

equipped with dynamic headlamp 
range control. As a result, the highway 
is always optimally lighted, regardless 
of load conditions, and drivers in 
oncoming traffic are not blinded. 

Xenon lamps make a significant contri-
bution to highway safety since other 
highway users, or bicyclists and motor-
cyclists in the right lane, and pedes-
trians are more easily detected.
