This Model stands aproximately 10cm tall (28'6'' or 8.7m) and features two Searchlight targets designed to fit one 3mm DualColor LED each. These DualColor LEDs are actually three colour LEDs as they can emit red or green light or both (which results in a bright orange colour, nearly yellow). Provided you have an apropriate DCC signal driver board this could be used to display solid red, green, yellow as well as flashing red, green or yellow aspects. Simpler wiring could include block signaling or turnout wiring or even toggle switches to be utilised for a specific aspect (displayed color).
Some prototype signals also have a white aspect which would require a 4-Pin RGB LED. So far I haven't been able to locate 3mm variants of that type. I have a target in devellopment that can fit a 5mm LED in the back which shines through a 3mm bore in the target. Wiring however is not trivial with this setup.
Shown above are three variants of each signal with left side, center and right side mounted targets. These will be offered sepearately in packs of one or three signals, as well as kits that can be assembled from a mast and individual targets.
Still missing grooves and bores to run the wires through.
