The first lighthouse was a 51-foot (16 m) high tower established in 1806, which was replaced by the current 81-foot (25 m) conical tower and a second order Fresnel lens in 1869. The lighthouse was automated in 1978 and is still operational. The foundation is a granite pier and the construction material is granite.
On May 12, 1881, the Galatea, bound from Providence, Rhode Island to New York, ran aground in the calm due to the dense fog. Two days later, the ship was able to get off the island without damage. The Lighthouse Board opened an investigation because it was suspected that the fog signal was not operational during that time. The naval officer in charge of the investigation, French Ensor Chadwick, spent time questioning witnesses and others who might have heard the signal, and tested the signal at various locations around Little Gull Island. He concluded that the fog signal was operational during the time as the signal was heard at Mystic, Connecticut and a tug boat that was farther away than the Galatea, and that the aberrations and eccentricities around Little Gull were even more significant than around Beavertail Lighthouse where sound tests were run later in 1881.
The US Coast Guard has identified Little Gull Island Light as one of its Historic Light Stations in New York. In 2009 Little Gull Island Light was put up for sale under the National Historic Lighthouse Preservation Act.
The sale of the Little Gull Light Station, established in 1869, broke the record for the highest bid received to date for lights under the National Historic Lighthouse Preservation Act. Located offshore in Long Island Sound, New York, the historic, 81-foot granite tower sits on one acre and was sold at a public online auction for $381,000. 
Little Gull Island Light is shown on the NOAA Chart 12354
The Archives Center at the Smithsonian National Museum of American History has a collection (#1055) of souvenir postcards of lighthouses and has digitized 272 of these and made them available online.
