Abstract: The invention relates to an automatic light system (ALS) for motor vehicles of all types. According to the invention the headlamp system is operated in such a manner that at every instant of the journey the minimum beam range does not drop below the instantaneous stopping distance (=braking distance+reaction distance) of the vehicle and the particular light intensity required is determined and set. This can be done for example by vertical pivoting of the headlamps or reflectors. Furthermore, the beam direction is adapted to the instantaneous steering angle.

Abstract: A vehicle cornering headlamp system which can be applied to any type of vehicle without changing the correspondence to a radiation angle, and which enables the radiation angle to follow the return of driver's eyes when the vehicle exits a curved road. The angular velocity .omega..sub.new is calculated at the time of travelling on a curved road on the basis of the output from an angular velocity sensor and the vehicle speed v is measured on the basis of distance pulses from a distance sensor.
