Underground subgenre for fans of hard working lighthouse- and fishermen. Can be identified by their thick wool sweaters, big beards and most importantly their use of a hand-held lantern (candle or oil).
Pipe smoking and use of phrases such as: "Is there anyone out there?" or "A storm is brewing..." are common in the community.
Dave: What the hell is John wearing? ...and is that a lantern he is holding?
Matt: Oh yeah, John is totally lighthousecore nowadays
Dave: Wtf?!
