Abstract
In a method for traffic dependent light width adjustment of light width for headlights in a motor vehicle, at least two image capturing units are provided whose pictures are forwarded to a control unit for evaluation. A control unit for controlling the light width of the headlights is provided, and on the basis of the captured pictures of both image capturing units a classification of the light sources outside of the vehicle is conducted. A distinction is made between oncoming, standing, and distancing light sources. With this classification the light width of the headlights is adjusted.
