Boca Grande lighghouse. The Gasparilla Island Lights are on Gasparilla Island in Boca Grande, Florida. The Port Boca Grande Light is on the south tip of Gasparilla Island, and marked the Boca Grande Pass entrance to Charlotte Harbor. It has also been known as the Gasparilla Island Light and the Boca Grande Light. The Gasparilla Island Light is one mile (1.6 km) north of the first lighthouse. It has also been known as the Boca Grande Light and the Boca Grande Light Rear Range. Lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses or, in older times, from a fire, and used as an aid to navigation for pilots at sea or on inland waterways. Lighthouses are used to mark dangerous coastlines, hazardous shoals and reefs, and safe entries to harbors, and can also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and replacement by modern electronic navigational aids.
