The Nore lightship was established as the world's first floating light ...
This represented a great step forward in lighthouse design. One such influence was Robert Stevenson, himself a seminal figure in the development of lighthouse design and construction. [7] His greatest achievement was the construction of the Bell Rock Lighthouse in 1810, one of the most impressive feats of engineering of the age.
An airway beacon (US) or aerial lighthouse (UK and Europe) was a rotating light assembly mounted atop a tower. These were once used extensively in the United States for visual navigation by airplane pilots along a specified airway corridor .
An electric light finally replaced the kerosene lantern in 1923, dramatically increasing the intensity of the signal.

The last civilian lighthouse keeper resigned, and the United States Coast Guard assumed responsibility for the beacon in 1946.

He created a new lighting system based on Argand lamps; in 1812 the United States Congress purchased his patent rights for the system ...
The original St. Simons Island lighthouse, which was built in 1810, was a 75-foot-tall (23 m) early federal octagonal lighthouse topped by a 10-foot (3.0 m) oil-burning lamp. During the American Civil War , U.S. military forces employed a naval blockade of the coast.
In the 1870s, 43 new lights were built on the Lakes. The 1880s saw more than one hundred lights constructed. [12] [13] As the new century began, on the Great Lakes the Lighthouse Board operated 334 major lights, 67 fog horns and 563 buoys. [12] [13] During the 19th century design of Great Lakes lights slowly evolved.
