Abstract:
A method is provided for increasing the robustness of a vehicle headlight comprising a cylindrical prism that can rotate about a rotary axis in a plurality of rotary positions and comprising a Hall effect sensor by means of the output signals of which the rotary position of the cylindrical prism can be determined. According to the method, a check is made as to whether a defect of the Hall effect sensor is present. In the event of a defect of the Hall effect sensor, a stop is temporarily provided and the rotary position of the prism is verified by being blocked at the provided stop.
