Uses the light pair examination in here. When has the signal input, the light pair TIL117 5 feet (C) outputs for the low level signal, examines the low level through the monolithic integrated circuit the time is red candle39。 counting down 0 foreword traffic signal control goes on a journey regarding the people have the vital significance, but the countdown may remind the people surplus time, attention street intersection traffic condition.
