ABSTRACT:
In a method for the automatic control of lighting devices, particularly of a motor vehicle, and a device for implementing the method, the brightness in a specific direction being detected by at least one directional sensor which emits direction signals to a control device, the control device switching on the lighting devices after a minimum time has elapsed. The minimum time begins when the direction signals exceed or drop below a switch-on threshold. The lighting devices are only switched on when the direction signals lie above or below the switch-on threshold during the entire minimum time. To that end, the control device is connected to a timer.
