The Northern Lighthouse Board, which manages the lighthouses of Scotland and the Isle of Man, is removing the mercury float at the 1821 Sumburgh Head Lighthouse, which is located about 100 miles off the coast of Scotland, on the southern tip of the main Shetland Island.
According to a story in the Shetland News by Chris Cope, the first order Fresnel lens, in the lantern of Sumburgh Head, is currently rotated on a float and mercury bath that will be replaced by a mechanical, motor driven bearing ring, which means the light will still rotate.
The Sumburgh Head Lighthouse Station is now owned by the Shetland Amenity Trust and was totally renovated in 1991. However, the lens is still owned and maintained by the Northern Lighthouse Board.
The red foghorn, seen in the photo, was discontinued in 1987 but was restored to working order in 2015.
