Admiralty Digital List of Lights (ADLL) is a comprehensive source of light and fog signal information. It uses the same official data as the Admiralty paper publication and includes lights, light vessels, major light buoys and fog signals. ADLL is provided on the complete Admiralty Digital Publications CD, but you can purchase just what you need - from one area of one product up to all areas of all products. ADLL is carriage compliant, approved by most Flag States and kept fully up to date. We can supply free trial versions; just provide your name and contact details and email a request.
Admiralty Digital List of Lights is recognised by most Flag States as meeting SOLAS carriage requirements. For the full list of Flag State Approvals click here.
