Yes, pulling power from the electrical AUX connector, splitting it to the
motor and the lighting system. I can get you some pics of the rear and a
quick scmatic of the working of the light system.
It's not that hard to do but it was a bit of a pain to get working. White
LEDs need 3.5volts to fire but a max of 4 volts before they burn out. So I
had to find a happy medium range to make it work.
I also used capasitors to smoth out the power to avoid flicker. It's not
perfect yet, the lights don't work on power level one on the controller.
I'll probally revisit that again.

| Dean, I'm guessing that you are pulling the electrical power for the lights from the track (thus allowing you to turn on only the direction needed), do you have an detail shots of how the lights are mounted? Looks good, congrats on the award. jt (...) (22 years ago, 9-Oct-02, to lugnet.trains)
