1. The signalling lights system of a vehicle consists of the stop lights, position lights and turn lights circuits, consisting of cables, fuses, switches and lamps. Characterized in that: the short-circuit signalling system (US) is introduced between the fuse (3), (6), (9) and the switch (2), (5), (8) of each of the circuits (1), (4), (7). The short-circuit signalling system consists of short-circuit signalling relays (11) and three negatively-polarised rectifying diodes (13), (14) and (15). The cathodes of the positively-polarised rectifying diode (16) and the relay (17) with shorted contact are connected. The system is also equipped with the interrupter (20), the double-throw switch (21), the control lamp (22) and the short-circuit signal lamp (23). The interconnection (24) of the cathodes of the negatively-polarised diodes (13), (14) and (15) is connected to the terminal (25) of the short-circuit signalling relay (11) coil (12). The other terminal (26) of the coil is connected to the terminal (27) of the short-circuit signalling relay (11), which is also connected to the active terminal of the switch (21) and to the power supply circuit (28). The other terminal (29) of the short-circuit relay (11) is connected to the coil (18) terminal of the relay (17) with shorted contact, and to the anode (30) of the positively-polarized diode (16). The cathode of the latter is connected to the (+-) terminal of the interrupter (20) and to the passive terminal (31) of the first position of the two-throw switch (21). The terminal (L) of the interrupter (20) is connected to the control lamp (22) and the short-circuit signal lamp (23) and to one of the terminals (33) of the relay (17) with shorted contact. The second terminal (19) of the relay is connected to the second passive terminal (32) of the second position of the double-throw switch (21). The anodes of the three negatively-polarised rectifying diodes (13), (14) and (15) of the short-circuit signalling system (US) are connected each to one of the lights circuits, i.e. the stop lights circuit (1), position lights circuit (4) and turn lights circuit (7). The second coil (18) terminal of the relay (17) with shorted contact and the second terminals of the signal lamp (23) and the control lamp (22) are connected to ground.
