Abstract

1288186 Transistor pulse generating circuits T J HEATH 20 April 1971 3148/71 Heading H3T [Also in Division G4] A flasher circuit adapted to be connected in series with the brake lamps of a motor vehicle is so constructed that the lamps can be made to flash on and off repeatedly when the brake pedal is not depressed but emit a continuous red light when the brakes are operated. The circuit, which is connected to the lamps and the power supply at A and B, comprises a multivibrator controlling the output of a power transistor or thyristor T3, the supply to the circuit being derived during the "off" period via the diode D1. The current flow charges C4 sufficiently for it to maintain a supply to the multivibrator during the "on" period. The capacitor C3 ensures that the lamps come on as soon as the flashing control switch is closed so that a warning signal is given as soon as possible. T1 and T2 may be F.E.T.'s.
