There were many lighthouses listed with no link nor any details, as a result of merging Florida lighthouses here. I think the list was of little use and just cluttered the article. It might be valuable for researching the topic, but for that finding the original page or this revision should be enough. I now pruned the list. --LPfi (talk) 11:01, 12 December 2018 (UTC)
In a recent edit shutter mechanisms are mentioned:
- They have complicated light sources, lenses, and shutter mechanisms to emit a unique identifying pattern of flashes.
In all lighthouses I have visited, the flashes are caused by the lens system, which rotates around the light. That system is mechanically more simple (although optically complex), with fewer parts that can break, and light is not wasted on a shutter.
- Fixed. The error was in the sentence structure, where it was unclear what was "complicated".
All entries on this page are now linked to a destination, but some lack a description in that destination. Content please for Isokari in Estonia, Alappuzha Kannur & Chennai in India, Scarborough Egmont Farnes & Alderney in Britain, and Port Hope in Florida. Grahamsands (talk) 16:15, 27 January 2019 (UTC)
