What is an aviation obstruction light?

Aviation obstruction lights are used to reduce the harm to all types of aircraft, such as airplanes, helicopters and drones, by indicating the existence of obstacles.
These obstruction lights can be fixed or moving objects. It should be marked to avoid the risk of collision near the airport or heliport.
In addition, it may be necessary to mark high-rise buildings in the air traffic area of aircraft or helicopters. These obstruction lights may be high-rise buildings, chimneys, transmission line towers, wind turbines, bridges, etc.
Aviation obstruction lights, also known as aircraft warning lights, are lighting equipment installed in high-rise buildings and used as anti-collision measures. Aviation obstruction lights make it easier for passing planes (such as airplanes, helicopters and drones) to see buildings, and they are usually used at night, although they can also be used during the day. According to the difference of Candeira, the intensity of aviation obstacle lamps can be low-intensity obstacle lamps (A-type low-intensity obstruction lights, B-type low-intensity obstruction lights, C-type low-intensity obstruction lights and D-type low-intensity obstruction lights), medium-intensity obstruction lights (A-type medium-intensity obstruction lights, B-type medium-intensity obstruction lights and C-type medium-intensity obstacle lamps), high-intensity obstruction lights (A-type high-intensity obstruction lights and B-type high-intensity obstacle lamps) and different types of aviation.
