Aviation obstruction lights are lighting devices indicating the presence of an object which is dangerous to an aircraft in flight. The obstruction light is to be mounted at the highest point of the wind cone assembly to make tall structures more visible to aircrafts during both daytime and nighttime. These devices should have specific features in terms of light intensity, beam pattern and light colour defined by international regulations and national standards. The majority of national CAA (Civil Aviation Authorities) use these recommendations as a basis to decide which structures need to have safety markings and to determine the design of the marking system required.
ICAO – International Civil Aviation Organization
ICAO is the international body responsible for drawing up recommendations for 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” which gives guidance concerning the need to provide safety marking on structures that may be considered to be a hazard to air traffic.

The document AC 70/7460-1K “obstruction marking and lighting” gives guidance concerning the need to provide safety marking on structures that may be considered to be a hazard to air traffic.
