    Guards Blue Light

    The LEDGBL GUARDS BLUE LIGHT is a safety light to advise patrons of the vicinity of the guard’s compartment in suburban rail cars. It comprises 88 LEDs [light emitting diodes] in four independent circuits, is powered from 77-137VDC and is supplied in a surface mount enclosure with an IP65 weatherproof rating.

    • High intensity LED’s with a 15 degree view angle up & down the side of the vehicle and 45 degree across the platform
    • Available in blue
    • Constant light, flashing or turned off
    • Ambient light sensor to automatically adjust light intensity for reduced intensity at night and greater light output during daytime. 
    • Nominal 120 [77-137VDC]
    • Plastic housing from random co-polymer polypropylene with 1% uv stabiliser
    • Approved to C tick
    • Low cost - High performance
    • Applications includes rail vehicles

    The LEDGBL warning light is an advanced instrument that have been designed and manufactured to stringent specifications. It has been designed to reject electrical interference that normally abounds in industrial environments.


    The light is intended to shine up and down the side of the train as well as across the platform. It has an array of 88 high contrast light emitting diodes (LEDs). Sixty four LEDS with a light emission angle of 15 degrees and twenty four with a light emission angle of 45 degrees. The LEDs are arranged in 4 independent circuits in three planes (2 rows of 22 in a horizontal band) so that the loss of one led will not cause total loss of light in one face. The LEDS are driven by a pulse width modulated current control circuit.
