Commissioners of Irish Lights

The Commissioners of Irish Lights (CIL) (Irish: Coimisinéirí Soilse na hÉireann ) is the body that serves as the General Lighthouse Authority for the island of Ireland plus its adjacent seas and islands. As the Irish Lighthouse Authority it oversees the coastal lights and navigation marks provided by the local lighthouse authorities; the county councils and port authorities.

It is funded by ships that use the seas around Ireland pooled with dues raised by the United Kingdom. This recognises that a large volume of shipping, typically transatlantic, relies on the lights provided by the CIL but never puts in to its ports.
