The United States Lighthouse Service, also known as the Bureau of Lighthouses, was the agency of the United States Government and the General Lighthouse Authority for the United States from the time of its creation in 1910 as the successor of the United States Lighthouse Board until 1939 when it was merged into the United States Coast Guard. It was responsible for the upkeep and maintenance of all lighthouses and lightvessels in the United States.
