Six bright and warm-white LEDs (5mm) preassembled with the required resistor and cable in order to equip a locomotive model (e.g. PIKO) with a triple head light on each side. Depending on the condition of the locomotive, the necessary number of LEDs are installed and connected to the decoder. The required resistor is already included in the cable to the LED so that connection to a function output with an output voltage of 5..22V is possible without problems and does not require special knowledge or programming. A second function output and the enclosed diode can also be used to implement a remote light function.
