1. A method for automatic control of lighting devices, comprising:
- detecting a brightness in a specific direction by at least one directional sensor which emits direction signals to a control device;
switching on the lighting devices by the control device after an expiration of a minimum time which begins when the direction signals;
and one of exceeding and dropping below a switch-on threshold; and
are one of above and below the switch-on threshold during the entire minimum time; and
determining the minimum time in view of an ambient brightness detected by at least one global sensor.

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.
