Aviation obstruction lighting
Aviation obstruction lighting is used to enhance the visibility of structures or fixed obstacles which may conflict with the safe navigation of aircraft. Obstruction lighting is commonly installed on towers, buildings, and even fences located in areas where aircraft may be operating at low altitudes. Aviation regulations may mandate the installation, operation, color, and status notification of obstruction lighting. Obstruction warning lighting systems commonly use one or more high-intensity strobe or LED devices which pilots can see from many miles away.
