FIELD: transport traffic control systems.
SUBSTANCE: invention relates to control and warning devices installed along the train route. Controlled LED traffic light comprises voltage source, signal relay contact, fire relay winding, group N in series and according to connected light-emitting diodes, anode of which is connected to first resistor output, a bipolar transistor whose base is connected to a cathode of a group of N light-emitting diodes, the emitter is connected to the negative terminal of the voltage source, and the collector is connected to the first terminal of the winding of the fire relay, the second output of which is connected to the positive terminal of the voltage source and through the contact of the signal relay is connected to the second terminal of the resistor.
EFFECT: higher reliability of operation of the traffic light control circuit.
