Abstract

A procedure is provided for actuating at least one main headlamp of a vehicle. The vehicle includes a detection device, and a light control for the automatic actuation of the main headlamp. The main headlamp illuminates an outer area of the area ahead of the vehicle in a first light intensity, and a core area of the area ahead of the vehicle at least partially enclosed by the outer area with a higher second light intensity. The core area is adjusted by the light control in terms of dimension and/or position. In order to improve the visual perceptibility to a vehicle driver of the area ahead of the vehicle, the core area is adjusted in relation to the outer area, and the outer area is adjusted by the light control in such a way depending on the input signal of the light control in terms of dimension and/or position that the vehicle's road and peripheral surroundings) bordering the road in the area ahead of the vehicle are illuminated by the outer area.
