alloboardWhat size LED voltage rating and brightness (mcd) should I use for HO scale signals like TexNrails' PRR position light signals without LED's?

Do you have the signals already? If not it might be a better idea to get signals with the LED's installed and save yourself a lot of headache. There are several good manufacturers. I think mine are by Tomar.

First thing - You will need to know what size the holes are in the signal. LED's come in many sizes. The voltage/amp rating can vary, but this is typical: 2-3 volts/20-25 ma current ratings. Most of the manufacturers list the MCD rating in thrir catalogs. Check out the Digikey and Mouser web site for their on-line catalogs. You might want to send an email to TexNrails and ask what they suggest for LED's.
