Aviation obstruction lights, also known as aircraft warning lights
or aviation warning lights, are used to increase the visibility of
tall structures or objects that could pose a hazard to aircraft.
These lights are typically installed on buildings, towers, cranes,
wind turbines, and other tall structures to make them more visible
to pilots, especially during nighttime or low-visibility conditions
low-intensity light could be used alone on the top of the High
rise Building, High Chimney, marking towers (Telecom, GSMMicro
wave & TV), High Pole, Tower Crane, Wind Turbine, etc whenthe h
eight is lower than 45m.
When obstacle object is higher than 45m, MF-LI-B2 can be used
with Medium-intensity or high-intensity obstruction light to
indicate
hazardous obstructions with a steady red safety light.
