The first lighthouses started operation on 30 October 1724, and were three towers lit by coal fires called St Peter, St Thomas and the Dungeon. Three stone towers were built to give the lights a distinctive appearance which would not be confused with lighthouses in nearby France. They were built by Thomas Le Cocq, owner of the rocks, under license from Trinity House and who was paid a halfpenny
Lighthouses on the Isle of Arran rebuilt between 1821 and 1830. Pladda was one of Northern Lights' lighthouses where paraffin as a new fuel together with multiple wicks were tested successfully in 1870. This allowed substantial savings with a simultaneous increase in power between 10% and 100%. Fog signals were introduced in the 1870s as well. In 1901, the formerly fixed light was changed to a more powerful group-flashing which was Northern Light's plan for most Scottish lighthouses at the time. Pladda lighthouse operates fully automatic since 1990. Pladdas position is 55° 25.512'N, 005° 07.113'W. Its light flashes Fl.(3)30s40m23M. The Inner lighthouse on Holy Isle faces
