Cape Henlopen is the southern cape of the Delaware Bay along the Atlantic coast of the United States. It lies in the state of Delaware, near the town of Lewes, where the Delaware Bay meets the Atlantic Ocean. Off the coast on the bay side are two lighthouses, called the Harbor of Refuge Light and the Delaware Breakwater East End Light.

Falkner Island Light, also known as the Faulkner Island Lighthouse, is a lighthouse in Connecticut, United States, on Falkner Island which is off Guilford Harbor on Long Island Sound. The lighthouse was constructed in 1802 and commissioned by President Thomas Jefferson. The lighthouse has had three keeper's houses: the original house of 1802 was rebuilt in 1851 and then again in 1871. The 1871 keeper's house survived to 1976, when it was destroyed by fire; the Coast Guard repaired and automated the lighthouse two years later. A volunteer group, the Faulkner's Light Brigade, has undertaken the restoration and preservation of the lighthouse since 1991, completing the last major restoration work in March 2011. Access to Falkner Island and the light is restricted during the nesting season of the roseate terns from May to August yearly. The Falkner Island Lighthouse, as the second oldest extant lighthouse in Connecticut, is listed on the National Register of Historic Places.
