Its foundation is a tank 14 feet (4.3 m) deep, which is kept filled with water to keep the 20-metre (66 ft)[2] (27 metres (89 ft) according to Rowlett)[4] reinforced concrete tower balanced and secured in the event of an earthquake.[2] The tower is topped with a lantern and gallery.[4]

An automatic white light 30 m (100 feet) above sea level flashes every two seconds.[4] The light was operated by gas initially, switching to acetylene in 1956 and solar energy in 1985.[2][3]

Several adjacent one-story frame keeper's houses are staffed.[4]

The site is a well-known attraction of the Negril area.[4]

It is maintained by the Port Authority of Jamaica, an agency of the Ministry of Transport and Works.[4]
