A lighthouse is defined as a structure erected to carry lights for warning or guidance of ships or aircraft . Lighthouses are usually located in or adjacent to navigable waters. They are designed to serve as visual guides by day and to provide a light during the night to warn mariners of danger and to help them chart a safe course. Identification by day is by the physical description of the structure of the lighthouse (example shape and colour). At nights, identification is by the characteristic flashes of the light. Many lighthouses are operated in conjunction with other navigational aids for example light buoys and beacons. 

Although the earliest lighthouse was built in 1841, it was not until 1886, that a law was passed authorizing the construction of lighthouses for the purpose of supplying lights at various points on the coast of the island, for the benefit of seagoing and coastal vessels.

There are several lighthouses strategically located across Jamaica. Below is a list of seven of the most important ones.

Negril Point Lighthouse, Westmoreland

This Lighthouse is situated at south Negril Point which is at the extreme western end of the Island. The concrete Tower which is painted white, stands 66 feet above ground level and the light is elevated 100 feet above sea level. The Lighthouse has an automatic white light which flashes every two seconds.

The Negril Lighthouse was built in 1894 by the French Company Bubbler & Bernard, on a tank 14 feet deep, which is kept filled with water. This is to keep the Tower balanced and secured in the event of an earthquake. The Tower which is built inland, is cylindrical and has an elaborate light enclosed in a metal and glass protector on top of which is a wind-wane.

 Initially, the Lighthouse was operated by a gas lamp, but in 1956 it was replaced by an acetylene gas lamp. This was used until 1985 when it was replaced by solar energy. 

The Lighthouse is located at latitude 18º 15' north and longitude 78º 23' west.
