ADLL - Admiralty Digital List of Lights

Admiralty Digital List of Lights (ADLL) is the world's leading source of light and fog signal information and provides full details of over 70,000 individual structures worldwide.


Simple Intuitive Interface

All information is displayed both in the traditional and familiar tabular form used in the paper publication and in a geographical window using familiar chart symbols.


Match Trading Patterns


ADLL can be customised to match trading patterns. Lights can be grouped and saved in special user-defined files to enable users to quickly retrieve information for specific routes and trading areas. Toolbars, screen layout and views can also be tailored to suit operational requirements.


Regular Updating


The use of digital technology allows the ADLL dataset to be updated quickly, accurately and with a minimum of manual intervention.


Comprehensive Search Facilities


The database can be searched either using the geographic window, text strings or geographic positions.


Full Print and Export Facilities


The details of lights and fog signals can be printed and exported into a range of other applications such as MS Word and MS Excel for use in activities such as passage planning.


Backup Licence

Each Licence includes a second backup licence provided free of charge to ensure that a vessel is never left without access to essential navigational information.
