What Is an Obstruction Light?
An obstruction light is an electric light designed as a marker to alert aircraft, ships, and surrounding areas to the presence of potential obstacles during nighttime or poor visibility conditions, aiming to prevent collisions.
These lights are mounted on various structures including tall buildings, communication towers, wind turbines, bridges, and offshore installations. Their critical role is to enhance safety by marking structures that could obstruct the navigation of aircraft and maritime vessels.
Obstruction lights consist of lamps, optical systems, control devices, and power supplies, working together to create a beacon that signals their location effectively. Their main features include high visibility to ensure detection from great distances, directional lighting to focus illumination where needed while reducing light pollution, and robust durability to endure extreme weather conditions like wind, rain, and snow.
