Abstract

Device for the detection of faults in lamps of automobiles. It comprises an intermittance control unit (11), which includes a relay and an osciler, connected to the positive and negative networks of the network and, separately, to a control lamp (19) through a polarization resistance (15 ), a pnp transistor (22) and a resistance (16). To the central (11) the main lamps (21) are connected through a resistance (14) and the contacts (20) of the steering wheel switch. Between the transistor p-N-p (22) and the control unit (11), a shunt (12) is intercuted, in another connection, whose output (23) is connected to the control unit (11), and the contact (13) of the relay. Failure of a lamp (21) causes a 50% voltage down in the shunt (12) that does double the oscillation frequency, detecting in the intermittance speed of the control lamp (19). Between the emitter and the transistor collector (22) the parallel diodes, zener diodes and/or tension dependent resistors (24) can be connected.
