Lighthouses
A lighthouse is a structure used to house a light source that acts as an aid to navigation for those at sea. It can also use a sound source for warning. They are also used to warn of dangerous coastlines, reefs, and other hazards, while indicating safe entries to harbors. Most remaining lighthouses are automatic rather than being manned. Questions should relate directly to all aspects regarding lighthouses, including their use and history.

From Wikipedia:
The Lighthouse of Alexandria, also known as the Pharos of Alexandria (in Ancient Greek, ὁ Φάρος Ἀλεξανδρινóς), was a tower built between 280 and 247 BC on the island of Pharos at Alexandria, Egypt. Its purpose was to guide sailors into the harbour at night time.
Constructed from large blocks of light-coloured stone, the tower was made up of three stages: a lower square section with a central core, a middle octagonal section, and, at the top, a circular section. At its apex was positioned a mirror which reflected sunlight during the day; a fire was lit at night.
With a height variously estimated at somewhere in-between 393 and 450 ft (120 and 140 m), it was for many centuries among the tallest man made structures on Earth. It was one of the Seven Wonders of the Ancient World. ...

Lighthouses use beams of light projected through a special lens called a Fresnel lens. Invented by a Frenchman in the early 1800s, the Fresnel lens concentrates beams of light through a prismatic lens which captures and concentrates them, so the light can be seen for many kilometres out at sea. The lens design uses a system of concentric glass rings to concentrate the light. This design is still used today in car headlights and traffic lights. Modern lighthouses have a system of rotating lenses, and newer lighthouses conserve energy by flashing the light on and off.
