In the offered traffic light use is made of three signal lamps, the color of glow of each of them is periodically changed in the process of optical signaling depending on the color signalized in the given time interval, the colors of the lamps are changed so that two lamps glow green or red, and the third lamp glows green, yellow or red providing for glow green or red of all three signal lamps in different time intervals, and glow yellow of one of the lamps.
