PURPOSE: An apparatus for wireless controlling the traffic signal light is provided to save the manpower required for the traffic control by controlling the traffic signal light in a remote control. CONSTITUTION: An apparatus for wireless controlling the traffic signal light includes a transmitter(100), a receiver(200), a signal controller(300) and at least one traffic signal lights(400). The transmitter(100) transmits the identification number of transmitter and the control signal to the receiver(200) with coding the control signal so as to change the traffic signal lights(400) and receives the reception confirm data of the control signal to change the traffic signal lights(400) from the receiver(200). The receiver(200) previously registers the identification number of at least one transmitters(100) to perform the wireless communication and identifies whether the transmitter is previously registered or not based on the identification number received from the corresponding transmitter. The receiver(200) transmits the data for identifying the reception of the control signal to change the traffic signal lights(400) to the corresponding transmitter(100). The signal controller(300) controls the turn-on and turn-off of the traffic signal lights(400) in response to the control signal to change the traffic signal lights(400). And, the traffic signal lights(400) turn on and off in response to the control of the signal controller(300).
