Thanks for the info captain that's what I thought the 21 pin decoder did " added more functions on board" . How did it help your 73 did you have to rebuild your front and rear light board ?An ESU 21-MTC decoder is currently limited to 4 LED outputs (white, yellow, magenta and green). A further two logic level outputs (Aux 3 & 4) are available via the 21 pin socket but they cannot drive LEDs directly. A transistor (BC547 and 4k7 ohm resistor) per output is required. The kit may include these components.
