Inside the light house at the source of the light.
The idea of creating a thinner, lighter lens by making it with separate sections mounted in a frame is often attributed to Georges-Louis Leclerc, Comte de Buffon.The marquis de Condorcet (1743�1794) proposed grinding such a lens from a single thin piece of glass.French physicist and engineer Augustin-Jean Fresnel is most often given credit for the development of the multi-part lens for use in lighthouses.
The light itself is a third order Fresnel lens that was made in France. It used to be fueled by lard, later it was fueled by kerosene, then by acetylene, and now by electricity.
