Threshold lights/end lights are installed to provide quick and positive identification of the threshold/end of a runway .
The color is emitted directly by LEDs in green or red depending on the viewing angle where red light towards the runway indicates the end of the runway for a departing aircraft and green light outwards from the end of the runway to indicate the threshold
of landing aircraft.
Runway Threshold-End Light Elevated is a bidirectional light with a lifespan of 60,000 hours.
The light complies with standards for ICAO and NATO:STANAG 3316.
