They also had a section covering the use of lighthouses in various media. Apparently St Anthony lighthouse was used in the show Fraggle Rock. Slightly more recent (and one I remember well) was the Australian show Round the Twist, wherein the Twist family live in a lighthouse. They also have this absolute gem of an advert based around the urban myth of the US aircraft carrier discovering that no, a lighthouse will not divert course to avoid a collision. And finally, there's this absolutely hilarious smith and Jones sketch.
That exhibition is being changed soon - instead they'll have one on search and rescue. Somehow they're going to fit a Sea King SAR helicopter into the exhibition space!
