The Bridgeport Harbor Light, later the Bridgeport Harbor Lighthouse, was a lighthouse in Bridgeport, Connecticut, United States. It is located on the west side of the Bridgeport Harbor entrance and the north side of Long Island Sound. Originally constructed in 1851 and rebuilt in 1871 with a dwelling, it had a red-fixed light throughout its service life. The builder and first keeper of the light was Abraham A. McNeil who is also credited as improvising the first light for the Bridgeport Harbor in 1844. By 1953, the lighthouse was in poor condition and the United States Coast Guard opted to build a skeleton tower in its place. In the 2014 edition of the Light List Volume 1, the skeleton tower is marked as "Light 13A" with a height of 57 feet (17 m) and a visual marker of a square green dayboard with a green reflective border. The lighthouse was sold and an attempt was made to move it to serve as a monument for Connecticut's maritime history, but it was later decided to scrap the structure. The lighthouse caught fire and was destroyed during the dismantling in 1953.
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 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.

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. In 1933, more than 30,000 tons of rocks from the excavation of Radio City Music Hall were added to the riprap foundation. The light was added to the National Register of Historic Places as Greens Ledge Lighthouse on May 29, 1990.
The Lynde Point Light or Lynde Point Lighthouse, also known as Saybrook Inner Lighthouse, is a lighthouse in Connecticut, United States, on the west side of the mouth of the Connecticut River on the Long Island Sound, Old Saybrook, Connecticut. The first light was a 35 feet (11 m) wooden tower constructed by Abisha Woodward for $2,200 and it was completed in 1803. A new lighthouse was eventually needed and a total of $7,500 was appropriated on July 7, 1838. Jonathan Scranton, Volney Pierce, and John Wilcox were contracted to build the new 65-foot (20 m) octagonal brownstone tower. It was constructed in 1838 and lit in 1839. The lighthouse was renovated in 1867 and had its keeper's house from 1833 replaced in 1858 with a Gothic Revival gambrel-roofed wood-frame house. In 1966, the house was torn down and replaced by a duplex house. The original ten lamps were replaced in 1852 with a fourth-order Fresnel lens, and with a fifth-order Fresnel lens in 1890. Lynde Point Lighthouse used whale oil until 1879 when it switched to kerosene. It was electrified in 1955 and fully automated by the United States Coast Guard in 1978. In 1990, it was added to the National Register of Historic Places and is significant for its "superior stone work in the tapering brownstone walls".

The Black Rock Harbor Light was an active navigational aid until 1933 when it was replaced by two automatic lights offshore. The beacon was subsequently given to the City of Bridgeport in 1934. Two significant efforts during the 1980s and 1990s served to restore the aging tower and the light was relit as a non-navigational aid in 2000.
