Aviation obstruction lighting from Aokux

Aviation obstruction lighting is a critical tool in preventing air traffic accidents. It is a lighting system installed on tall structures, such as towers, wind turbines, and buildings, to provide visibility to pilots in low-visibility conditions. In this article, we'll explore the different types of aviation obstruction lighting and how they work.

There are three types of aviation obstruction lighting: low-intensity, medium-intensity, and high-intensity. Low-intensity obstruction lighting is used for structures that are shorter than 45 meters (148 feet) and is typically composed of steady burning red lights with a minimum intensity of 10 candela. Medium-intensity obstruction lighting is used for structures that are between 45 and 150 meters (148 and 492 feet) and typically consists of flashing red lights with a minimum intensity of 20,000 candela. High-intensity obstruction lighting is used for structures over 150 meters (492 feet) and consists of flashing white lights with a minimum intensity of 200,000 candela.

Different colors of obstruction lighting are used for different structures. For example, red lights are used for structures over 150 meters (492 feet) or in proximity to airports, while white lights are used for structures between 45 and 150 meters (148 and 492 feet).

Obstruction lighting technology has evolved to incorporate LED lighting which is more energy-efficient, durable, and longer-lasting than traditional lighting systems. LED lighting also allows for more precise control of lighting patterns and intensity.


In addition to height and color, the placement of aviation obstruction lighting is also critical. The lights need to be placed at the highest point of the structure and positioned so that they are visible from all angles. The FAA sets strict guidelines for the installation and operation of obstruction lighting to ensure the safety of air traffic.

In conclusion, aviation obstruction lighting is a critical safety feature for tall structures that can pose a threat to air traffic. The use of different colors and lighting intensities provides pilots with critical information about the height and proximity of structures. As technology continues to evolve, obstruction lighting systems will become even more efficient and effective in keeping our skies safe.
