"Lighthouses are designed to emit light from a system of lamps and lenses and used as a navigational aid for maritime pilots at sea or on inland waterways."
Lighthouses are not spiraled, they are towers.
Lighthouses are typically unmanned and automated, and do not require people to operate them. The light beams are now usually powered by electricity and controlled remotely. In the past, lighthouses did need keepers to maintain the light and equipment, but advancements in technology have made this role unnecessary.
