Abstract

A device for controlling a driving light of a vehicle includes a headlight with a light source, a device for pivoting a produced light distribution and an optical element that provides adjustable light distribution. The optical element includes a light passage opening pivotable into an optical axis of the light source. A beam of the light distribution is limited or deflected such that a limited light field is produced in a pre-settable region in front of the vehicle, which light field has an external form of the light passage opening. Further light passage structures provide a “high beam” or “partial high beam” light pattern and thereafter the “high beam” light pattern by turning, pivoting and/or displacing the optical element in one direction, and another further light passage structure provides a “motorway” and thereafter a “country road” light pattern by turning, pivoting and/or displacing the optical element in an opposite direction.
