Those are pretty badman (the rest of your RS looks great!). The ones on my ST that sat outside for 7 years were in much better shape, and I replaced them with some foreign knock offs from ebay. Of course they weren't HIDs or LEDs, either, and were much cheaper to replace.
If I were you; I'd consult with a body shop or professional detailer for advice. Good luck!
