WEEKLY LIGHT LISTS

The USCG Light List is provided annually and is intended to furnish more complete information concerning aids to navigation than can be conveniently shown on charts. The Light List is not intended to be used in place of charts or Coast Pilots. Charts should be consulted for the location of all aids to navigation. It may be dangerous to use aids to navigation without reference to charts.

Mariners are cautioned to keep their Light Lists, charts and other nautical publications corrected and should consult all notices issued after the date of publication of the annual Light List. A summary of corrections for the annual publication, which includes corrections from the dates shown on the title page to the date of availability, is available at the Light List Corrections page. These corrections must be applied in order to bring the Light List up-to-date. Additionally, this publication should be corrected weekly from the Local Notices to Mariners or the Notices to Mariners, as appropriate.

The links below are weekly updates to the Light List corrected through the LNM week displayed on the header of each page. The weekly Light Lists are provided in two formats: PDF and XML. The XML Light List file contains aid information only: Light List Number, aid name, position, light characteristic, height, range, structure information and remarks. The weekly PDF file displays the Light List in traditional format. Front matter and indices are updated annually and are accessible at the link provided as well as in the full light list book.

These data sets are provided for the convenience of the user and are provided "as is" and without warranties of any kind either expressed or implied.

NOTE: Beginning 2/5/2015, Volume V, Mississippi River System will add aid latitude and longitude (in addition to River Bank/Mile) in the XML file only.

Disclaimer: Weekly Light List updates are provided in PDF format. XML files of selected Light List fields (LLNR, Aid Name, Position, Light Characteristic, Height, Range, structure and remarks) are also provided as a public service for data research.
