摘要： In a circuit arrangement for monitoring an electronic switch provided for controlling a load and current flown through the load during turn-on intervals for driving the load, the switch has a substantially linear resistance behavior during parts of its turn-on state and the operating point of the switch is located in this part of the turn-on state during the load control. The circuit arrangement comprises a modulation signal generator for generating a modulation signal for modulating the load current flowing through the electronic switch. A first voltage measuring device measures the first voltage drop across the electronic switch caused by the modulation signal. A second voltage measuring device measures the voltage drop across the electronic switch caused by the load current, and an evaluation unit determines the load current from the modulation signal and the first and second voltage drops.

摘要： In a headlight including a housing supporting a reflector with a bulb and having an opening for handling the bulb, a hood of elastic material is provided, which closes the opening from the rear side of the housing. An annular sealing lip is provided on the hood itself which in assembly lies against the outer surface of the conical ring portion formed on the rear wall of the housing. An open hinge with bellows and a tongue, engageable with a shoulder on the rear wall of the housing, is provided at one side of the hood and a snap arrangement is provided on a diametrically opposite side of the hood to secure the hood to the housing.
