<P> This is a list of lighthouses in the United States . The United States has had approximately a thousand lights as well as light towers, range lights, and pier head lights . Michigan has the most lights of any state with over 150 past and present lights . Lighthouses that are in former U.S. territories are not listed here . </P> <P> Most of the lights in the United States have been built and maintained by the Coast Guard (since 1939) and its predecessors, the United States Lighthouse Service (1910--1939) and the United States Lighthouse Board (1852--1910). Before the Lighthouse Board was established, local collectors of customs were responsible for lighthouses under Stephen Pleasonton . As their importance to navigation has declined and as public interest in them has increased, the Coast Guard has been handing over ownership and in some cases responsibility for running them to other parties, the chief of them being the National Park Service under the National Historic Lighthouse Preservation Act of 2000 . </P>
