[0005]

According to the light emitting stop line system having the above structure, when the illuminance detecting means of the transmitting unit detects, for example, a sunset state, the vehicle detecting means switches the road toward an intersection or a T-shaped road. When the operation of detecting a vehicle traveling on the vehicle is started and the traveling vehicle is detected, the wireless signal transmission circuit transmits a signal in the form of a radio wave based on the detected signal. This signal is received by a receiving circuit provided in a light emitting unit disposed at an intersection or a T-shaped intersection where the traveling vehicle travels. When the receiving circuit receives this signal, the light emission control circuit causes the light emitter to blink and emit light by intermittently applying a voltage from the power supply circuit to the light emitter.
