The Northern Lighthouse Board (NLB) is a public body responsible for the management and maintenance of lighthouses and navigational aids in Scotland and the Isle of Man. Established in 1786, its primary goal is to ensure the safety of maritime navigation by providing reliable lighting and signaling systems for ships. The NLB operates a range of lighthouses, buoys, and beacons, using modern technology to enhance their effectiveness. It also engages in research and development to improve maritime safety. The board works closely with other organizations, such as the Maritime and Coastguard Agency, to coordinate efforts in ensuring safe passage for vessels in northern waters.
