I believe I've seen two members here use the ISx50 taillights on their Fs. From what I've seen, it looks to be a direct fit. I'm not sure about the wiring, but for the most part, they should be transferrable.
There's some kind of a tab difference and the harness needs to be changed. Do a search, I'm sure you'll find it. I've thought of the same thing. I really like the swoosh taillights.
