Aviation obstruction lights (Aircraft warning lights)

Led Aviation obstruction lights (Led Aircraft warning lights) 


Aviation obstruction lights (Aircraft warning lights) are lighting devices that are installed to high structures and are used as collision avoidance measures. Aviation obstruction lights make structures more visible to passing aircraft and are usually used at night, although they can be used during the day as well. Aviation obstruction lights need to have sufficient brightness in order to be visible for miles around the structure.

International Civil Aviation Organization (ICAO) is one of the leading authority that has regulations and standards about aircraft warning lights. Due to the height of the structure, the quantity and intensity of the aircraft warning light can vary.

The air traffic has increased exponentially and the use of aircraft warning lights have become either a must or recommendation for most applications. Municipalities, states and governments may have regulations concerning requirements of high structures. So, marking the high structures and making them more visible to aircrafts, can be a legal duty according to the location.

Considering ICAO Annex 14, FAA aviation regulations and existing applications, red color aviation obstruction light is widespreadly used. Also various color options are available such as yellow, orange, blue, green, white color aircraft warning lights can be preffered for different applications.

Generally, aircraft warning light (AWL) system includes microprocessor and photocell. In most cases, photocell is used to detect insufficient ambient light, and the aircraft warning light starts working ( steady or flashing mode).
WETRA LED aircraft warning lights uses LED (light-emitting diode) technology which enables long life-span (100.000 hours) ,high light per heat efficiency, low electricity consumption, low heat loss Wetra aircraft warning light meets IP 65 standards. The policarbon cap of Wetra aviation obstruction lights is splashproof.

Manufacturer and Supplier of Best Aviation Obstruction Lights 

WETRA LED aviation obstruction lights also have options such as; single/twin, flashing/steady burning mode, with/without photocell, different voltage values and solar options according to your needs.  

Aviation obstruction lights are also named as aircraft warning lights, obstruction marking light, mast obstruction light, led aviation obstacle lights.

The International Civil Aviation Organisation (ICAO) is the international authority responsible for  regulations regarding the safety of air transport. The Convention on International Civil Aviation, Annex 14 Volume I "Aerodrome Design and Operations" includes Chapter 6 "VISUAL AIDS FOR DENOTING OBSTACLES" that states guidance concerning the need to provide safety markings on structures that might be considered to be a hazard to air traffic. The majority of national domestic Civil Aviation Authorities (CAA) also apply these recommendations as a basis to decide which structures need to have safety markings, and to determine the design of the marking system required.
