In 1779, as British sailors retreating from Newport near the end of the American Revolutionary War, they left a trail of destruction behind them. This included burning the lighthouse and removing the optics, which left the light dark for the rest of the war.
In 1856, the tower was again replaced with what is now the current tower, made of granite which is 10 ft (3.0 m) square, and 64 feet (20 m) from ground to beacon. A 3rd order Fresnel lens was placed and over the next forty years it was the site of numerous fog-signal tests, under the supervision of the United State Lighthouse board. In 1898 quarters for an assistant keeper were added to the keeper's house, the assistant helped, among other things, with fog-signaling.
During the 1938 hurricane, the whistle house was destroyed, revealing the original base for the 1749 structure, which sits 100 feet (30 m) from the current tower. A few miles southwest of Beavertail point, Whale Rock can be seen, resembling a submarine attempting to surface. Whale Rock Lighthouse, and its keeper, Walter Eberle, were swept into the waters of Narragansett bay during the hurricane of 1938; Eberle's body was never recovered.
In 1939, the US Coast Guard took command of all lighthouses and navigational aids, and in 1989 Beavertail light was automated, as part of a program by the Coast Guard, which ended the job the keeper at all stations except for Boston Light, which to this day, remains the only manned lighthouse in America.
In 1989, following a joint effort by the US Coast Guard, Rhode Island Parks Management, the Rhode Island Department of Environmental Management, and the town of Jamestown, the building was restored and reopened to the public. In 1993, Beavertail Lighthouse Museum Association (BLMA) was established to oversee the operations of the Beavertail Lighthouse Museum, which is located in the assistant keeper's house. The museum includes a Fresnel lens, and the history of, models and photos of many Rhode Island lighthouses.
