  A rather distant Streetview.

  The lighthouse itself is from 1835, per the NIAH

  Wikipedia says: A bell was established at Roche's Point in 1864 to warn mariners in poor visibility. This was replaced by a siren fog signal on 1 December 1898. The fog signal changed again in 1949 when a diaphone was installed with a character of one two-second blast every thirty seconds. In 1995 when the lighthouse was automated an electric fog signal (ELG 300–04) replaced the diaphone. This electric fog signal was connected to a fog detector which activated the fog signal if visibility fell below three nautical miles. The electric fog signal had a range of four nautical miles. On 11 January 2011 the Commissioners of Irish Lights, despite much opposition, discontinued all Irish fog signals. This brought an end to a long era of fog signaling at Roche's Point. I think it is likely we are looking at the engine/compressor for the 1898 fog signal.

  Here is a page about Campbell engines. The example on that page runs on "1.15 pounds of Russoline oil per hp per hour". Googling Russoline oil does not tell me much except that it was a Russian petroleum oil: The ordinary burning oils sold in Britain are American oils, Royal Daylight, Ordinary, Water White, and Tea Rose. The Russian oils are Russoline and Russian Lustre. The paraffin oils are Broxbourne Lighthouse, Young's paraffin oil, and similar oils by many other makers.
