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.
