High Intensity Type A Aircraft Warning Lights (ICAO & FAA Standard) for Wind Turbines

-

 As wind energy continues to grow globally, safety remains a top priority—not just on the ground but also in the sky. Tall wind turbines, often located in open landscapes or offshore, must be equipped with reliable aircraft warning systems to prevent aerial accidents. One of the most critical components in this system is the High Intensity Type A Aircraft Warning Light, designed in accordance with ICAO and FAA regulations.

What Is a Type A High Intensity Aircraft Warning Light?

Type A lights are high-intensity white flashing obstruction lights used for structures over 150 meters (approx. 500 feet) above ground level. These lights provide visibility from long distances both during the day and night. They are particularly suitable for tall structures such as:

  • Wind turbines

  • Communication towers

  • Chimneys

  • Transmission line pylons

  • Skyscrapers in remote areas

These lights typically flash at 40 FPM (flashes per minute) and have an intensity range of 2000cd (candela) at night to 20000cd during daytime.

ICAO and FAA Compliance

Our high intensity obstruction lights fully comply with:

  • ICAO Annex 14 – Volume I, Chapter 6

  • FAA Advisory Circular 150/5345-43 and L-856 standard

This means they meet international and U.S. safety regulations for marking tall obstacles in or near air routes. The automatic brightness control adjusts the intensity based on ambient lighting conditions, reducing light pollution at night while maintaining safety.

Why Are These Lights Important for Wind Turbines?

Wind farms are increasingly located in areas that may interfere with air traffic, including near rural airports or helicopter routes. ICAO and FAA standards require any turbine exceeding specific height thresholds to have warning lights installed.

Benefits include:

  • Increased aerial safety: Prevents collision risks in low visibility.

  • Automatic control: Day/night sensor and flashing controller built-in.

  • Durability: IP65 or higher protection rating for tough weather conditions.

  • Energy efficiency: Available in solar or low-power versions.

  • Modular design: Easy installation on turbine nacelles or towers.

Technical Highlights

  • Flash Intensity: 2000–20000cd

  • Flashing Rate: 40FPM

  • Input Power: AC or 48VDC options

  • Control: Built-in photocell + remote monitoring (optional)

  • Weatherproof Design: Operating temperature -40°C to +55°C

Conclusion

Installing ICAO/FAA-compliant Type A high intensity aircraft warning lights is not just about regulatory compliance—it's about protecting lives and infrastructure. Whether you're building a new wind farm or retrofitting an existing one, choosing the right warning light system is essential.
