The arrangement has an ambient light intensity sensor with global and directional sensors and an evaluation device for comparing the sensor signals with threshold values and switching on the illumination devices if a signal falls below at least one threshold value. Temperature-dependent basic sensor signals for no incident light are stored in the evaluation device and used to correct the current sensor signals and/or threshold values. The arrangement has an ambient light intensity sensor with at least one global sensor and at least one directional sensor for the driving direction and an evaluation device for comparing the sensor signals with threshold values and switching on the illumination devices if a signal falls below at least one threshold value. The current sensor temperature is detected at least indirectly and temperature-dependent basic sensor signals for no incident light are stored in the evaluation device and used to correct the current sensor signals and/or threshold values.
