Xenon lamps*

The xenon lamp provides forward illu-

mination with significantly more bright-

ness and uniformity than the traditional

halogen lamp.

In a xenon lamp, an electric arc replaces

the filament in order 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. Maxi-

mum 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).

Xenon lamps make a significant contri-

bution to highway safety since other

highway users, bicyclists and motorcy-

clists in the right lane, and pedestrians

are more easily detected.
