I am trying to install traffic lights for my N scale model railroad. I purchased and built a Velleman MK131 Traffic Light Kit (see attached diagram). The kit has a Common Ground connection for the three LEDs. However, the Traffic Light units have a Common + connection for the LEDs. Is there a voltage conversion circuit I can employ or is it as simple as adding a full wave rectifier to each LED output. Any and all assistance would be greatly appreciated.
