It is one of 33 sparkplug lighthouses still in existence in the United States and remains an active aid to navigation. It sits in ten feet of water on the west end of Greens Ledge, a shallow underwater reef that runs a mile west of Sheffield Island and is roughly a mile south of the entrance to Five Mile River at Rowayton. Completed in 1902 by the Philadelphia Construction Company, the cast-iron structure is approximately 90 feet tall including roughly 15 feet of the submerged caisson.

Southwest Ledge Light is an active lighthouse marking the main entrance channel to the harbor of New Haven, Connecticut. Completed in 1877, it was one of the first to be built on a cylindrical iron foundation, an innovation by Maj. George H.
