A light element connection circuit of a light emitting diode signal lamp is provided to maintain LED signal lamp easily by connecting emitting devices connected with a parallel line linked with a power line. In a light element connection circuit of a light emitting diode signal lamp, a plurality of emitting devices(LED1-LEDn) are arranged on a PCB within a traffic signal main body. A plurality of parallel lines(L1-Ln) is connected with the power line of the PCB, and One emitting device(LED1) and one resistor(R1) are serially connected with each parallel line while the resistors are corresponds to emitting devices respectively. |
