The Essex Reef Light or Essex Reef Post Light, also known as Hayden's Point Light, was a light in Essex, Connecticut on the Connecticut River. The 21-foot (6.4 m) wooden tower was erected in 1889 and replaced with a skeleton tower by 1919. The skeleton tower was further altered to an automatic gas light a few years prior to 1931. Two of the keepers, Gilbert B. Hayden and Bernie Hayden, relation unknown, were keepers of the light, but their service years are unknown. As of 2014, a 26-foot (7.9 m) skeleton tower serves as an active daymark and it has a green flash every 4 seconds.
