Pro Tech's realistic looking True Scale "LED" Searchlight Signals are high quality photoetched signals.
They are designed from real life railroad signal dimensions to produce a 'true scale' appearance.
This signal is preassembled and ready to install.
This signal contains a green LED that has a current limiting resistor already installed. You can connect it directly to your transformer's (DC) track voltage or any DC supply of 2-16 volts.
Not to be operated on AC current.
This signal is also available with a "Bi-Color" LED (Green/Red) that changes color with change of track voltage polarity.
