Position light STM.804 series

for airport runwaywarningfor airport

Overview
The STM.804 Elevated Runway Guard Light (RGL) provides a clear visual warning at runway holding positions. The unit uses two side-by-side unidirectional LED modules producing alternating flashes: STM.804.RGL.01(Y) in yellow or STM.804.RGL.02(R) in red, at 45–50 flashes per minute. A fully autonomous solar variant integrates a high-efficiency solar panel and battery system while meeting ICAO and FAA photometric requirements.
