200mm full screen yellow flashing countdown traffic light, using imported super bright LED chip, high brightness with long life. Low voltage 24V luminous circuit power supply, circuit stable safe and reliable easy to maintain, LED by constant current source control and stable current sound. Branch circuit adopts shunts parallel to the current flow through each LED relatively balanced, Countdown for the learning-oriented adaptive countdown, need not use data directly and lane lamp power connector can; Countdown adopts imported microcomputer chip, stable and reliable performance, circuits installed hardware watchdog, make the countdown more stable performance.
