The Commissioners of Irish Lights are the General Lighthouse Authority for all of Ireland, its adjacent seas and islands.

CIL's Vision Statement is to deliver a reliable, efficient and cost effective Aids to Navigation service for the benefit and safety of all Mariners.

In addition, there is an obligation on CIL to inspect and approve the AtoN systems and to audit the subsequent management of AtoNs provided by Ports and local Lighthouse Authorities.

The Board requires the highest standard of professional competence in the planning and management of the service.
