History
Ushenish Lighthouse was designed by engineers, David and Thomas Stevenson. Established in 1857, it incorporated a new 'condensing' apparatus developed by Thomas Stevenson as an improvement to the dioptric system. The lighthouse was automated in 1970, one of the first major automatic lights. The gas-operated Dalen beacon was monitored from Neist Point Lighthouse, on Skye.[3]
