Obstacle lighting is governed by legislation. The UK’s Civil Aviation Authority has stipulated that any structure more than 45m must have medium intensity AWLs when in the vicinity of an aerodrome. In February this year the Civil Aviation Authority (CAA) revised CAP 168 –Licensing of Aerodromes to take into account the developments of LED technology as aeronautical visual aids.

Delta Obstruction Lighting is launching a medium intensity red LED aircraft warning light that includes a power supply switch to reduce electricity usage. The company claims the LEDs last five times as long than neon or incandescent lights.

Earlier this year, Lancsville Construction installed replacement aircraft warning lights on their two huge tower cranes at the Barratt Homes site in Battersea, London.
