This island lighthouse is situated on the SE side of the prominent high island (also known as 'Paddy's Milestone') from which it takes its name. It guards the W side of the main entrance into the Firth of Clyde, and is notable for the addition of a complex system of fog signals.

Built by Thomas and D A Stevenson, the light was established in 1886 and automated in 1990. Two fog signals (in 'horn houses') were established at opposite ends of the island in 1883-6, being powered by gas supplied from a central gasworks (NX09NW 5.01) just NW of the tower. These were replaced by a Tyfon system (situated close to the tower) in 1966.
