30 St. Joseph Pier Light(s) (MI 49,50)

Note that this is actually 2 lights set on a pier to provide a "front range" "rear range" combination.  Note also the catwalk provided so that even when the pier is awash, the Coast Guard can get to the light (not that I'd want to walk out there in that kind of weather).
