A device for controlling the brightness of dashboard lights in a motor vehicle is described, where an optoelectric receiver adjusts the light intensity of the dashboard lights with the output signal as a function of ambient brightness. To obtain an automatic measurement of the ambient brightness distribution in the direction of vehicle travel, taking into account the brightness in certain regions in the vicinity of the vehicle, an image sensor pointing in the direction of vehicle travel is provided as an optoelectric receiver to perform a location-selective absolute brightness measurement, and its electric output signal, weighted with preselected or preselectable algorithms for determining ambient brightness by an analyzer unit, so it can be sent to a control unit to influence the brightness of the dashboard lights. |
