International Lighthouse/Lightship Weekend
The fact that a light has been listed in official documents such as the "British Admiralty List of Lights and Foghorns" or the "US Coast Guard list of Navigation Aids" and also the ARLHS World List of Lights, does not automatically qualify the structure for this event.
Lights such as range lights, channel markers, skeletal towers ,and breakwall lights will probably not be accepted.
Here are some examples of some lights which have been submitted for the event but
which have been rejected for non-compliance with the guidelines and the spirit of the event.
