@Jeffery Boat posted:Thanks for asking Ray. I wired them to the 14 volt accessory post on my Lionel TW transformer.
Jeff, I looked at the manual for those lights on the Lionel site, from what I could see it looks like the lights do not have a diode in the wiring, that may be the problem of operating them on ac power, I request John to weigh in on that. Look at the link attached.
