Abstract

A method for changing at least one light emission parameter of a headlamp system or a vehicle headlamp of a motor vehicle based on changing ambient light conditions. The light emission parameters of the headlamp system are stored in a memory of a computer at the factory. The ambient light conditions in the driving direction of the motor vehicle are detected by a sensor and forwarded to the computer. Actual light emission parameters of the headlamp system and the ambient light condition are compared and a change of at least one of the light emission parameters of the headlamp system or the vehicle headlamp in accordance with the ambient light conditions forwarded is determined that a predefined or predefinable threshold value or limiting value of the current actual light emission parameters is exceeded.
