Abstract

In a vehicle headlight system with a light source (2) and at least one reflector (1) for shaping the light emitted by the light source into a high beam and a low beam, and with a shield (7) adjustable via an actuating element (9) between a position in which the light from the light source (2) is blocked across a maximum cross section and an essentially transmissive position in which this light is substantially allowed to pass through, the actuating element (9) adapted for adjusting the shield (7) in a plurality of intermediate positions between the maximal blocking and the essentially transmissive position in which intermediate position the blocked cross section is less than the maximal cross section.
