Fresnel lenses are becoming history

(autotranslated, could have mistakes)

In 1851, the United States Congress passed a law requiring all lighthouses to be equipped with Fresnel lenses, a law that is still technically in effect today. However, as time and modern technology move forward, Fresnel lenses are being removed from lighthouses. Together with them, the lighthouse charm is somewhat lost, because... Modern LED systems do not produce the same charming impression as ribbed Fresnel lenses.

Text of the 1851 law: “That hereafter, in all new lighthouses requiring new lighting apparatus, and in all lighthouses yet unsupplied with illuminating apparatus, the lens or Fresnel system shall be adopted.”
