The lighthouse you are describing is the Solitude lighthouse. The lighthouse I'm talking about is the Frostflow lighthouse, which is halfway between Dawnstar and Winterhold. It did not need to be turned on.

I don't know how to turn the Solitude lighthouse back on, and shame on you for shipwrecking those poor sailors.
