Summary of regulations on Obstruction light.

High Intensity Flashing White Lighting Systems

High intensity lighting systems are more effective than orange/red and white paint under certain ambient light conditions involving the position of the sun relative to the direction of flight and therefore may be recommended instead of marking. When operated 24 hours a day, other methods of marking and lighting may be omitted. High intensity lighting systems are not recommended on structures of 150m AGL or less.

The characteristics of this light comply with Annex 14 chapter 6 table 6-3. Red aeronautical obstacle lights on top of structures that require marking shall be dual units for redundancy purposes unless the system is monitored and failed units can be replaced within one working day.
