The lighthouse was illuminated in 1849 and the current tower was first lit in 1871. The lighthouse was deactivated in 1959. The foundation is wood pilings and stone and the construction is brick and wood shingle. The tower is octagonal with a white lantern. In 1893 a fifth order Fresnel lens and a new Funck lamp were installed, replacing a Sixth Order Fresnel lens that was installed in 1871.
Dean Kamen now owns the island, where he has installed advanced illumination and isolated it from the power grid.
