What is the purpose of obstruction lighting?

Obstruction lighting exists to make tall or potentially dangerous structures visible to pilots, both at night and in conditions where visibility is impaired. By marking the presence, location, and often the height of towers, antennas, chimneys, wind turbines, bridges, and similar hazards, these lights help air crews see and avoid obstacles, reducing the risk of mid-air or ground collisions. The other ideas don’t fit as the primary purpose: the lighting isn’t about imparting height information directly, preventing bird strikes, or indicating wind direction; it’s about providing a clear visual cue of hazards to air navigation.
