That's the one, Dennis. Thanks.

So the list of bird-cage lantern room lights still standing (or in parts) includes:

Bailey Harbor (Old) WI
Cape Henry (Old) VA
Cape St. George FL (Not presently standing, but hopes to)
Prudence Island RI
Selkirk NY
Waugoshance MI

I've seen and photographed five of the six (missed Cape St. George FL; I've got to make a Gulf Coast trip sometime.)
