OO Gauge Modern GPLS (Red - Red / White - White Shunt Signal)

A modern version OO gauge GPLS (ground position light signal). The signal displays white / white or red / red and is mounted on a concrete plinth. The signal uses micro LEDS inserted into the signal head rather than using LEDS under the baseboard with light tubes resulting in easier installation and far superior performance. Fitted with resistors for 9 - 16V DC working.
