Abstract
The invention relates to a device for influencing a lighting installation, and more particularly, includes a lighting installation of a motor vehicle, depending on ambient light. The device comprises a switching device to turn the lighting installation on and off. At least one optical sensor is provided to detect the wavelength of the ambient light. An evaluation device sends a control signal to the switching device when the wavelengths of the ambient light detected by the sensor are essentially those contained in the daylight. Since the filter and the sensor are jointly formed by at least one light emitting diode which operates as a light-sensitive element, the passing lights can be automatically turned on in a simple and favorable manner.
