The PRO APF L-804 RGL Runway Guard Light is a critical safety fixture designed to enhance the visibility of taxiway holding positions and prevent runway incursions by alerting pilots when they are approaching an active runway. This lighting system typically consists of two RGL fixtures installed at each end of the holding position line. Each fixture features two signal heads that alternately flash, providing a clear and unmistakable warning to pilots.
Certified under FAA AC 150/5345-46 Current Edition as L-804 and compliant with FAA Engineering Brief 67D as well as ICAO Annex 14 Figure A2-25, the PRO APF L-804 RGL meets rigorous international standards for airfield lighting and safety.
The design of the PRO APF L-804 RGL incorporates ETL certification, reflecting its adherence to stringent electrical safety and performance requirements. It utilizes two 21-watt LED optical assemblies, which offer an average LED lifespan of approximately 50,000 hours. The use of LEDs significantly reduces circuit load compared to traditional lighting technologies, enhancing overall energy efficiency.
This runway guard light operates seamlessly with FAA constant current regulators, compatible with both 3-step and 5-step circuits. It features an adjustable light beam elevation, which can be precisely set and positively locked in one-degree increments to ensure optimal visibility and performance tailored to specific airport requirements.
With a minimum average intensity exceeding 3,000 candelas in traffic yellow, the PRO APF L-804 RGL provides high visibility even in challenging daylight conditions. The fixture alternately flashes its signal heads at a rate of 45 to 50 times per minute, creating a distinctive warning signal for pilots.
Maintenance considerations are well integrated into the design. The fixture is easy to maintain without requiring special tools, and it includes an external ON/OFF switch option that allows field personnel to perform maintenance safely without needing to de-energize the entire power loop. This feature improves operational safety and minimizes downtime.
The PRO APF L-804 RGL is constructed with a high-strength frame and durable aluminum housing, ensuring robustness in demanding airport environments. Each signal head is fitted with an independent black visor to protect against adverse weather conditions and to enhance contrast during bright daylight, improving the light’s effectiveness.
For mounting, the fixture includes a 2-inch frangible coupling and tether at its base, along with a 12-inch anti-rotation locking plate to secure the installation. The system is designed to withstand jet blast forces up to 300 miles per hour, making it highly resilient in high-traffic airport areas.
Additionally, the base unit is equipped with a dry contact output for monitoring purposes, enabling integration with airport lighting control systems. Computer control and monitoring options are also available, and customers are encouraged to consult with the factory for assistance in configuring these advanced features.
In summary, the PRO APF L-804 RGL Runway Guard Light combines durability, visibility, energy efficiency, and ease of maintenance to deliver a reliable and effective runway safety solution for airports worldwide.
