Wind turbine obstruction lighting reference configuration
● Install two obstruction lights on top of the nacelle, separated by more than the width of a turbine blade.
● Obstruction lights on the same wind turbine should flash in synchronization.
● For total wind-turbine heights <45 m, install Type B low-intensity or Type B medium-intensity lights at the top.
● For total wind-turbine heights ≥45 m and <105 m, install Type B medium-intensity lights on top of the nacelle.
● For total wind-turbine heights ≥105 m and <150 m, install Type A medium-intensity lights on top of the nacelle.
● For total wind-turbine heights ≥150 m, install Type A high-intensity lights on top of the nacelle and low-intensity lights at 1/2 of the nacelle height.
