A method and an apparatus for automatic control of illumination devices, in particular of a motor vehicle, include a brightness sensor which delivers first signals, the illumination devices are switched off after a time interval that begins at the point in time at which the first signals exceed or fall below a first threshold. The length of the time interval is modifiable, and in particular, is capable of being extended.
