Detailed introduction
Medium intensity obstruction lights, specifically Type AB, are essential components of aviation safety systems. These lights are designed to mark tall structures, such as towers or buildings, that could pose a potential hazard to aircraft navigation. Type AB obstruction lights combine the features of both Type A and Type B lights, offering a comprehensive solution for enhanced visibility.
Type A lights are flashing white lights that provide a constant visual cue of the structure's presence during nighttime operations. On the other hand, Type B lights are flashing red lights that increase visibility during the day and in low-visibility conditions. By combining these two types of lights, Type AB obstruction lights ensure optimal visibility for pilots in all lighting and weather conditions.
Compliance with international aviation regulations, including those set by the International Civil Aviation Organization (ICAO) and the Federal Aviation Administration (FAA), is a fundamental requirement for Type AB obstruction lights. Regular maintenance and inspections are crucial to ensure their proper functioning, including checking for any damage, verifying alignment and visibility, and promptly replacing any faulty components.
By clearly marking tall structures with medium intensity obstruction lights, specifically Type AB, pilots are provided with a clear visual cue to maintain a safe distance and navigate their aircraft accordingly. This significantly enhances aviation safety and helps prevent potential accidents caused by obstacles. The durability and reliability of Type AB obstruction lights make them an essential safety measure for structures, ensuring the overall safety of air traffic and protecting both aircraft and structures.

Overview:
Medium intensity obstruction light Type AB Type AC AO-MI-AB2, it flashes white color daytime and red color night time. According to ICAO, FAA regulations, this obstruction lights aviation is designed for marking top of obstacle wich height is 45-105-150m. and this aircraft obstruction light needs to keep working in 24 hrs. We adopt high intensity CREE LEDs as light source, stable quality and long life time.
Compliance:
1. International Civil Aviation Organization (ICAO), Aerodromes, Annex 14, Volume 1, Eighth Edition, dated July 2018
2. FAA L-864, FAA L-865.
Features:
1. Adopt super bright CREE brand LED, high intensity with a lower energy consumption.
2. Input voltage available in DC(12-48V DC) or AC(100-265V AC 50-60Hz).
3. Unique design and UV protected polycarbonate for the obstruction light protect cover.
4. Efficient photometric design provides excellent light distribution, make sure meet ICAO and FAA demand.
5. Base material is die casting aluminum which has strong corrosion resistance, Shock and Vibrations protection, long time service time
6. Special valve installed under the base to make sure the air could go through but water is avoid, so that the whole FAA Obstruction Lighting ICAO Type A C A B Obstruction Light Aircraft Warning Lights temperature won’t be high.
7. Built-in photocell for daytime and night operation.
8. Surge and lightning protection.
9. Kinds of optional functions available, such as GPS synchronous flashing, sequence flashing, alarm relay etc.
