PRO TECH's True Scale Signals are high quality photoetched signals (non-LED).
This 3-lens N scale searchlight signal has three individual lenses and is designed from real life railroad signal dimensions to produce a 'true scale' appearance.
The upper lens is green, while the bottom two lenses are red.
PRO TECH's True Scale (non-LED) Signals are high quality photoetched signals.
These signals differ from our other "LED" units as they are non-operational. This allows the modeler a choice to purchase a high quality photoetched signal at a much lower cost than that of an operating signal.
