light station

noun, lighthouse (COD); see also light

“Each fog station and light station on the Great Lakes had a different time. Like, I’ll give you an example. Nine Mile up here, when the old schooners used to come in, she had a three second light flash every thirty seconds. The horn blew a three second blast every thirty seconds. So these old timers, when they come in, they didn’t have to, for an example, see the light but they could time the horn.”
