led signals

[Anonymous]

I am attempting to put oregon rail signals on my underconstruction ho layout. I need to know if the leds would be connected to DC or AC power? Also can they be wired to a switch turn on them on and off for the N and S directions? Sorry for a stupid question but I know nothing about wiring. A switch seems to be the cheapest way to go when one can't afford the DCC, and other things needed.

Thanks for your time

You will get the best results with this question, by reposting it over on the Model Railroader board, in the layout building section. The people on this board are used to dealing with O gauge trains and not too many LEDs.
