My favourite bit about people who use OpenStreetMap data for lighthouses is that they end up including <https://www.google.com/maps/@52.2647013,-2.1151705,51a,15y,2...> lighthouse in the exceptionally landlocked Droitwich (shows up as Hanbury Wharf Lighthouse)
They also often include "pairs" of lighthouses (high / low, front / rear) where newer ones have replaced older ones, but the older structure is still there (and often is now a museum), but isn't the active lighthouse.
Although this one has done a reasonable job at culling most of those out, at least on the south coast of England.
