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 hook up directly to your transformer's (DC) track current or any DC supply of 2-16 volts.

Not to be operated on AC current.

These signals are also available with a "Bi-Color" LED (Green/Red) that changes color with change of track (voltage) polarity.

Here is an in depth review of this N scale signal by C Mastracci. See his YouTube channel here.
