Abstract
A headlight arrangement of a vehicle having a reflector subdivided into a plurality of reflector regions, a light source arranged in a region of an apex of the reflector so that a light emitted by the light source is reflected by the reflector onto a roadway in front of the vehicle, at least one screening device associated with at least one of the reflector regions, the screening device being adjustable between a position in which the light emitted by the light source can reach a selected one of the reflector regions, and a position in which a light emitted by the light source is at least partially screened from a selected one of the reflector regions, and a control unit which controls the screening device in dependence on vehicle sensor signals and adjusts the screening device so that in each vehicle situation an optimal light distribution is provided.
