Admiralty Digital List of Lights (ADLL) is a comprehensive source of light and fog signal information. It uses the same official data provided in the Admiralty paper publication and includes lights, light vessels, major light buoys and fog signals.
ADLL is updated weekly. Each week's updates can be downloaded in a matter of seconds over a standard internet connection or via email, and are applied automatically.
Admiralty Digital List of Lights is recognised by a number of Flag States as meeting SOLAS carriage requirements for its paper counterpart. For the full list of Flag State Approvals click here.
