The Hillsboro Inlet light station was built in 1907. It has been given to a non-profit organization for historical preservation and public education. The Lighthouse Service, created in 1789, became part of the Coast Guard in 1939. The tradition of ensuring the safe navigation of the seas that began with the running of lighthouses continues today. The Coast Guard maintains the "signposts" and "traffic signals"--more than 50,000 federal aids to navigation, including buoys, lighthouses, day beacons, and radio-navigation signals--on the nation's waterways.
