The present invention relates to a system for detecting the fault of a traffic light and, more particularly, to a system for detecting the fault of a traffic light, capable of reducing costs consumed for detecting the traffic light and preventing a traffic congestion by quickly dealing with the fault by accurately determining the fault or abnormality of each LED lamp comprising the traffic light and transmitting the determination result to a control center in real time. For achieving the purpose, the present invention includes a fault detecting module which is formed in the traffic light, a server which receives the state of the traffic light detected in the fault detecting module in real time, and the control center which is connected to the server. The fault detecting module includes a current monitoring unit which detects a current when a plurality of LED lamps are operated and a control unit which determines the fault or abnormality of the LED lamp according to the current value detected in the current monitoring unit.
