Abstract
1419427 Signalling apparatus on vehicles E KULLENBERG 31 Jan 1973 [10 Jan 1973] 4871/73 Heading G4Q A motor-vehicle blinker circuit comprises a silicon power transistor 1 whose emittercollector circuit includes parallel-connected lamps 2 and to whose base is connected the collector of another transistor 4, preferably also a silicon transistor, a potential divider 5, 6 whose tapping point is connected to the base of the transistor 4 and further including a capacitor 7 connected to the collector of the power transistor 1. An additional capacitor can be placed in parallel with the capacitor 7 when additional lamps 2 are added and the flash frequency is to be maintained the same.
