Abstract: A signal lamp is disclosed for use in automotive vehicles. The lamp includes a housing, a reflector for producing parallel rays, a lens closing the housing in the direction of light exit and diaphragms mounted behind the lens. The outside of the lens is provided with non-reflecting or weakly reflecting transverse stripes to avoid undesired reflections. In one advantageous embodiment, the diaphragms are positioned only in an upper portion of the lamp.

Abstract: An electric drive unit particularly adapted for actuating windshield wiper assemblies includes a motor having it's armature shaft carrying aportion having two oppositely pitched worm threads. Two worm gear wheels are disposed each on opposite sides of the threaded portion and in engagement therewith. The axes of rotation of the worm wheels are in parallel. Two spur wheels are each concentrically seated on a respective worm wheel. The spur wheels each engage a wheel having its axis of rotation located in a plane defined by the axes of rotation of the worm wheels. The toothed wheel is connected to a drive shaft.

Abstract: An automotive turn-signal flasher unit in which an astable transistor multivibrator periodically switches a flashing circuit through a switching relay is disclosed. The switching relay is formed as an electro-mechanical buzzer and thereby simultaneously provides the additional function of a separate acoustical signal source such as a buzzer.
