Who approves nonstandard obstruction lights?

The key idea here is who has the authority to approve lighting configurations for obstructions near airports. In the United States, that responsibility rests with the Federal Aviation Administration. The FAA oversees aviation safety, including the marking and lighting of obstructions to air navigation, and it has the authority to approve nonstandard lighting when standard solutions don’t fit a particular situation. This ensures that any deviation still provides clear, consistent visibility to pilots and does not create new hazards. The other organizations have different roles: the NTSB is responsible for investigating accidents and making safety recommendations, not granting approvals; ICAO sets international standards but does not issue domestic approvals; DOT is the parent department, with the FAA as the agency that actually handles approvals. So, when nonstandard obstruction lights are considered, the FAA is the proper approving body.
