Abstract
Circuit arrangement for operation of incandescent lamps in motor vehicles. A circuit arrangement for operation of incandescent lamps in motor vehicles, having the following features: input connections (J1, J2), which are coupled to a vehicle power supply system supply voltage (UB), with the vehicle power supply system supply voltage (UB) essentially being a DC voltage, output connections (J3, J4), which are coupled to incandescent lamps (Lp), characterized in that the circuit arrangement contains an inverter which, at the output connections (J3, J4), provides an output voltage (UA) which is essentially an AC voltage.
