摘要

The automobile headlamp (1) has a reflector (2), a light source (3) and a setting device (4) with an electromagnet (7), used for switching between the different lighting functions under control of an end stage (11) receiving a clocked control signal (13). A noise suppression filter circuit for the end stage is provided with at least one choke element (17), formed as a conductor path applied to a printed circuit board.
