LED on a stick (scratchbuilt N-gauge signal)

[tv_man]

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.

I used the exact same principle here. I gave some thought to how to make 3 or 4 LED signals, but it seems one would need a bit more wiring for that. Did you come up with any tricks to keep the number of wires to a minimum? I can't think of less than 5 wires for a 4 LED signal.

Transformer wire seems indeed to be useful for these things (and smaller modeling projects in general..)

The LEDs are 1,8mm sized (that's what they are listed as) They have a 3x2x2mm box underneath and a 1,8mm diameter bulb on top. Which makes them approximately correctly sized for use in N as is.
