Gas Discharge Headlights
Gas discharge headlights, which are integrated
into the headlights, are available for the Passat
as an option.
However, the use of gas discharge technology
is limited to the dipped beam headlight
because it takes up to three seconds to achieve
maximum luminous intensity. Therefore, H4
halogen lights will continue to be installed for
the main beam headlight.
Advantage of gas discharge headlights:
-
Greater luminous efficiency than
conventional headlights
-
Better brightness distribution by virtue of a
lens
-
Fog light is no longer necessary

On acount of the greater danger of dazzling
oncoming traffic, vehicles with gas discharge
headlights are equipped with dynamic head-
light range control.
Consequently, the switch for the manual head-
light range control is not required.
Electronic Headlight Range Control
This function gathers its information on body
tilt angle relative to the vehicle axes from two
sensors located inside the front and rear wheel
housings on the left-hand side of vehicle.
