I'm pretty low tech with electrical projects but I've been wanting to have some sort of illuminated signals for a long time. I finally decided to go with bi polar red/green LEDs to create indicators of track polarity. That's useful at this location where hidden track is sometimes used for staging. Its good to have a way of knowing for sure which way trains on hidden track are going to move! 
Any way, I soldered LEDs, resistors and lead wires, and threaded them through a Bachmann signal bridge. Here are the resutls:
