Reply to "Need assistance identifying these O Scale Track Signals and what is needed to get them to operate correctly."

I am pretty sure those early models were all GOW bulbs and not LEDs. The triple target SA style used a green bulb in the upper target a yellow one in the center target and red in the lower target. I remember seeing these very early around 1980. The other style you have is preferred to as the ā€œGā€ style also used red,green,yellow targets, The SA style in real life uses a single lamp housing with a lens that rotates inside to allow each target to illuminate all three colors from one lamp. Good thing about those early NJI signals they were easy to rewire converting to LEDs. If you need help you can reach me at Atlas Model railroad 908-687-0880 ext 7142.
