Hello I am trying to install a reversing headlight in an old cast medal locomotive boiler. DCC is not an option here. I would like to use LEDs if possible. Thank you for any help you may offer.
Hi, you should be able to just wire a 3v white led of your choice in series with a 1k ohm resistor directly to track power.
Depending on the polarity you wire it to track, itll be lit in either forward or reverse. Id test it one way, and if it lights up going forward, just switch the polarity.
This is a quick n dirty method. Ideally you also wire a proper diode into the circuit.
