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. Its keeper, Gilbert Burnett "Bernie" Hayden served for 30 years. 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.
