In a circuit arrangement for a reversible electric motor for directly driving a windshield wiper the motor is operated at reduced rotational speed in predetermined angular ranges to ensure smooth starting and stopping in the reversing positions and an accurate parking position.

Windshield wiper speed control arrangement

An illuminating device for use in an automotive vehicle for panel lighting, in which the holder carrying the panel lighting incandescent lamp is composed of two electrically conductive contact plates, between which is inserted an insulating foil plate. The two conductive plates are superimposed and fixed to each other with the foil plate between, whereby the contact webs or terminals for connecting the incandescent lamp are integrally formed out of these contact plates.

Illuminating device

A windshield wiper control circuit is described wherein the time at which the wiper motor is deenergized after an operating switch has been switched off is determined by the wiper speed. The parking position of the wiper is thereby independent of the condition of the windshield.
