Xenon lamps
*
The xenon lamps light up the side and
front areas of the vehicle with signifi-
cantly more brightness and uniformity
than the traditional halogen lamp.
In a xenon lamp,
an electric arc re-
places the filament in order to generate
intense illumination. A gas mixture in a
quartz piston 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 period of high inten-
sity. Maximum brightness is attained in
approx. 15 seconds.

Xenon lamps
provide significantly-im-
proved visibility, especially during ad-
verse weather conditions and driving
situations (driving at night in heavy rain
or through road repair areas where
there are no lanemarkers, for instance).
Vehicles with xenon lamps are
equipped with automatic-dynamic
headlamp range control. As a result, the
highway is always optimally lighted, re-
gardless 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, bicyclists and motorcy-
clists in the right lane, and pedestrians
are more easily detected.

Water and dirt repellent windshield
*
With this windshield (not released at
this time), a specially-smoothed surface
causes water drops to bead up and run
off, thus carrying particles of dirt with
them.
Traditional windshields, even when they
are in new condition, have a microscop-
ically "rough" surface (1). The surface of
the water and dirt repelling windshield
is smoothed with a clear transparent
fluid.
Depending on the cleanliness of the
windshield, the water beads up and
runs off at approx. 40 mph (60 km/h) as
a result of the air flow (2). The coating
has no negative effect on vision through
the windshield because it is completely
transparent.390de337
Additional benefits:
>Clear vision in adverse weather con-
ditions, resulting in enhanced driving
safety
>Less glare when driving in the rain at
night.
