A local lighthouse authority (LLA) is a port, harbour, or other party providing navigational aids in a locality as part of its facilities. These local authorities subscribe to the general lighthouse authority's policy on the correct maintenance and provision of such equipment.
Funding for the three GLAs is primarily collected through light dues, which are pooled in the General Lighthouse Fund and dispersed to the three authorities. The Irish Government also makes a contribution to the GLF.[1]
The powers of Trinity House and the Northern Lighthouse Board are currently established in the Merchant Shipping Act 1995.[2] These include the inspection of aids to navigation provided by local lighthouse authorities, and the levying of light dues on vessels to fund their work. The Dublin Port Act 1867 (30 & 31 Vict. c. lxxxi) established the Commissioners of Irish Lights, as successor to the Irish Lights Department of the Corporation for Preserving and Improving the Port of Dublin, as the agency responsible for all Irish coastal lights.[3]
