On September 5, 1933, a flashing white light of 280 candlepower was established on a white skeleton pyramidal tower on Boyer Bluff, the northwesterly end of Washington Island. The light had a focal plane of 215 feet and was visible for eleven miles.
In 2012, the light produced a white flash every six seconds, had a focal plane of 220 feet, and was located atop a sixty-seven-foot-tall tower.
