LED on a stick (scratchbuilt N-gauge signal)

[TCWORLD]

I had some similar scrathbuilt signals on my last n-gauge layout, they are indeed very fiddly to build. I got some 1.6mm x 0.8mm LEDs, a pair soldered such that when the polarity was one way it was green, and when it was the other it was red. I also managed a 4-LED model which allows independent control of all 4 LEDs. I plan to make 15 more for my new layout.

Streetlights can be made in a similar way.
