Abstract
An electrical switching system for adjusting the brightness of the dashboard lights of a motor vehicle includes a switch provided with a switch lever, for switching between low beam and high beam. Improvements are made whereby the brightness and dazzle-free character of the dashboard lighting can be adjusted with regard to the situation of low beam or high beam. This is achieved in that a switch between brighter dashboard lighting and less bright dashboard lighting is provided which is associated with a switch lever which can be moved to "high beam" and "low beam" positions. Dazzling of the driver due to excessively bright dashboard lighting, and lack of visibility due to inadequately bright dashboard lighting are avoided.
