Tower obstruction lighting reference configuration
● For tower heights ≤30 m, install one low-intensity obstruction light at the top.
● For tower heights 30 < H m ≤45 m, install one twin low-intensity obstruction light at the top.
● For tower heights 45 m < H ≤90 m, install one Type B medium-intensity light at the top and one low-intensity light at 1/2 of the height.
● For tower heights 90 m < H ≤150 m, install one Type A medium-intensity light at the top and Type B medium-intensity or low-intensity lights at 2/3 and 1/3 of the height.
● For tower heights ≥150 m, install Type A high-intensity lights at the top and Type B medium-intensity lights at other levels.
