FAA L-810 AC LED Marker 370

for Tower Lights and Obstruction Lighting Systems

Flash Technology marker lights feature a proprietary integrated monitoring circuit that interfaces with the Vanguard® Medium FTS 370 and Vanguard Red FTS 371 controllers to accurately monitor multiple LED marker configurations used in telecom and industrial obstruction lighting.


These compact and efficient L-810 marker lights reduce operating costs through nominal power consumption and extended longevity. An added advantage is that they easily install onto existing marker bases without disturbing the existing conduit.
