AH-HI-A2 LED High-Intensity Type A Aviation Obstruction Light Successfully Installed on Telecom Tower
2026/07/31
Project Overview
A cutting-edge AH-HI-A2 LED High-Intensity Type A Aviation Obstruction Light has been successfully installed and commissioned atop a major telecommunications tower, marking a significant enhancement in aerial navigation safety. The installation, completed using a custom-fabricated mounting bracket, ensures the tower is clearly visible to low-flying aircraft under all weather conditions, 24 hours a day.
Why This Installation Matters
Any structure exceeding 150 meters in height poses a serious hazard to aviation if not properly marked. Telecom towers, with their slim profiles and remote locations, are particularly difficult for pilots to spot — especially during nighttime or adverse weather. Installing a compliant high-intensity obstruction light is not merely a best practice but a critical safety obligation recognized by international aviation authorities worldwide.

Key Operational Highlights
1. Intelligent Day-Night Adaptation
The built-in photocell continuously monitors ambient light levels and automatically adjusts output intensity: ≥100,000 candelas during daytime for maximum visibility, ≥20,000 cd at twilight, and ≥2,000 cd at night. This dynamic adjustment ensures both optimal safety and energy efficiency, fully compliant with ICAO standards.
2. Extreme Environment Ready
The AH-HI-A2 is engineered for the harshest conditions. Its IP67-rated housing guarantees complete dust ingress protection and submersion resistance, while the corrosion-proof die-cast aluminum base with UV-stable powder coating withstands decades of sun, rain, and salt exposure. A unique breather valve equalizes internal pressure and expels moisture without compromising the waterproof seal, preventing heat buildup that could degrade internal components.
3. Comprehensive Surge and Lightning Protection
Tall towers are natural lightning attractors. The integrated surge protection circuitry shields the LED driver and control electronics from voltage spikes caused by nearby lightning strikes or grid instability, dramatically reducing downtime and replacement costs.
4. Optional Advanced Synchronization
For installations requiring multiple lights — such as super-tall structures with obstruction lights at several height tiers — optional GPS synchronization ensures all units flash in perfect unison. Additional available upgrades include infrared LEDs compatible with Night Vision Goggles (NVG), dry-contact alarm outputs for remote monitoring, and RS232 communication ports for centralized control.
Conclusion
This successful deployment demonstrates the AH-HI-A2's suitability for mission-critical aviation safety applications on tall infrastructure. And full ICAO compliance, it represents a reliable, cost-effective solution for telecom operators, wind farm developers, and high-rise facility managers seeking to meet their aerial obstruction marking obligations.
