Which government organization regulates tower lighting?

The Federal Aviation Administration (FAA) is the government organization that regulates tower lighting. The FAA's regulations are primarily concerned with ensuring aviation safety by requiring structures that may pose an obstruction to air traffic, such as communication towers, to be marked and lighted appropriately. This is crucial for preventing accidents and ensuring that pilots can see these tall structures from a distance, especially at night or in poor visibility conditions.

The regulations set by the FAA include guidelines on the color, intensity, and flashing patterns of lights on towers, which are vital for distinguishing them from other aerial obstructions. The FAA coordinates with other stakeholders, including telecommunications companies, to ensure compliance with these safety standards.

While the FCC oversees communication regulations, OSHA focuses on occupational safety, and FEMA deals with emergency management, none of these organizations address the specific requirements related to aviation safety concerning tower lighting like the FAA does.
