Abstract
A control system for vehicle headlights includes a navigation device and a control unit which controls the illumination characteristics of the headlights depending on geographic location information received by the navigation device. The illumination characteristics are adapted in compliance with predefined illumination settings if the acquired geographic location information shows that the vehicle headlights are being operated on public roads. The illumination characteristics are adapted with further consideration of illumination settings specified by the driver if the location information shows that the vehicle headlights are being operated on non-public roads.
