ABSTRACT:
A method and device for automatically switching on and/or off the illumination of a vehicle. Faulty switching is reduced by adapting the threshold value for switching on the illumination by averaging the measured brightness value(s) according to the driving speed and using switching-off conditions which, inter alia, consider the surrounding brightness.
