The S4GA medium intensity runway threshold identification light (RTIL, or REIL) is a solar-powered airfield light that flashes white and can be remotely controlled. It provides a permanent, reliable lighting solution for civil and military airports while also serving as a backup system for airports with wired lighting infrastructure.
The S4GA Solar Runway Threshold Identification Light features advanced GPS Synchronization technology with onboard GPS receivers for synchronization. Its internal synchronization system seamlessly integrates with GPS receivers. Utilizing signals from overhead satellites, multiple lights synchronize their flashes at 60 FPM, enhancing visibility and safety.
