Solar Elevated Runway Guard Lights (ERGL)

24-hour Unidirectional Marking at Airfield Intersections

Flash’s solar elevated runway guard lights (ERGL) provide a distinctive warning to pilots that they are approaching a runway holding position and are about to enter an active runway. The ERGL has a high intensity LED light source and is powered by our industry-leading solar engine power supply (SEPS). The ERGL installs in minutes with no trenching, cabling or external power, and can be relocated just as quickly.


An ideal choice for airfields that require improved safety measures but experience difficulties with grid access, a solar ERGL makes it even easier to retrofit existing runways with this effective and preventative solution.


  • Runway guard lights provide 24-hour unidirectional marking at runway and taxiway intersections
  • The solar ERGL nstalls in minutes and can be relocated just as quickly
  • Includes LED lights, frangible column and tether
  • The flash rate of the runway guard light is controlled from an intelligent lighting control system module located in the SEPS; alternating flashes, 45–50 per minute
  • Adjustable light beam can be aimed both vertically and horizontally – 0-20° vertically, ±20° horizontally
  • Significant reduction of maintenance costs and relamping expenses through long-lasting LED technology—average LED life of 56,000 hours under high-intensity conditions and more than 100,000 hours under actual operating conditions
  • Engineered for reliable performance, the energy management system (EMS) monitors and adapts brightness to environmental conditions for consistent operation and long life under tough conditions
  • 7+ days of autonomy (operation without solar charging), scalable to meet requirements up to 40 days
  • 5+ years of battery life


SEPS Models

The ERGL is available in 2 SEPS models, standard and wireless. With the standard SEPS, the unit will activate automatically between dawn and dusk with pre-set illumination. The wirelessly-controlled SEPS allows the unit to be activated remotely via the Handheld Controller, with either 900 MHz or 2.4 GHz communication.


Fixture Construction

The elevated RGL fixture is fabricated from corrosion-resistant materials and all exterior surfaces are painted aviation yellow for added protection and visibility. Includes high-strength ERGL base plate. The 2 ERGL light sources are surrounded by a black faceplate and independent visors to reduce the amount of incident sunlight, thereby maximizing the contrast during the LED on/off cycle.



RGL systems are typically installed in pairs with one unit on either side of the taxiway holding position. The ERGL should be installed according to FAA AC 150/5340-30. The SEPS should be installed on a level concrete pad within 20 feet of the ERGL. For a temporary application, the wiring between the SEPS and the ERGL can be above ground. Both the ERGL and SEPS contain side conduits for cabling access.
