mination with significantly more bright-
ness and uniformity than the traditional

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.

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-

are more easily detected.
