Abstract

A method for controlling two lighting modules of a headlight, including the following steps: definition of a non-dazzling region, wherein the non-dazzling region is at least within the second region; reduction of the brightness of the light emitted by the two lighting modules toward the non-dazzling region; determination as to whether an adjacent region exists that directly adjoins the non-dazzling region horizontally and that is a horizontal edge region of the first region; and reduction of the brightness of the light emitted by the first lighting module toward the adjacent region if the adjacent region has been determined.
