John Warren's Album: dwarph yard signals

Photo 1 of 4 in dwarph yard signals

Single dwarf signal on right is my first attempt.
Above I making a double light signal out of round and square styrene tube, some leds (with flattened face) a bit of shrink tube and 2 1K resistors. It will be easier to use a red/green led, however I don't have any and just using what I have an make do with it.
My back to back yard ladders are a bit confusing to visitors and I occasionally run a turnout myself ( actually its mostly me, just kidding ;) .
Anyhow I cant afford the 7 dollar signals at the LHS, besides its more fun to just tinker.
