How are light lists published for U.S. coastal waters characterized?

Light lists for U.S. coastal waters are published and characterized as being correct only to the date of publication. This means that the information contained within the light list reflects the status of navigational lights, aids, and other critical information only up to the time it was published. After that date, changes to any lights, such as new installations, modifications, or deletions, may not be reflected until the next publication.

Navigators must remain aware that any alterations to navigation aids or discrepancies that arise post-publication need to be verified through more current resources or notices, such as Local Notice to Mariners or Coast Guard bulletins, in order to ensure safety during navigation. This highlights the importance of checking for updates beyond the light list publication to maintain safe and compliant navigation practices on U.S. waters.
