What color is the lens on the rotating beacon used for larger obstructions to aid longer-range identification?

Red is used because it provides strong long-range visibility and a clear warning signal to pilots. The red hue stands out against a variety of backgrounds and lighting conditions, making a tall obstruction recognizable from farther away. Blue or green lights are associated with other airport lighting or signaling schemes, and yellow is typically used for caution rather than a definitive obstruction warning. So red is the standard choice for a rotating beacon on large obstructions to aid longer-range identification.
