- Two units of medium intensity red obstruction lights are at the top of the turbine nacelle, red flashing 2000cd±25%
- At least three units of OL200 low intensity single obstruction light are at midway between the top of the nacelle and ground level
- All medium intensity and low intensity lights in the wind turbine come with built-in GPS module, for flashing synchronously at 30FPM (±3fpm)
- All turbines at the height of 210-315m should install L-864 medium intensity lights and L-810F low intensity lights, regardless of their location within a wind turbine farm.
