worty,
the yellow lenses are not correct for the CS, and the /322 is in reference to fog lights, but just make sure they are fog lenses and not running lights. Now for other lenses, I believe Hans also sells 653's and 651's, these also come in running and fog lights, they are not correct for the CS but you can almost not tell the difference. You would have to get within a foot to see any difference, I know this because I have a set of both. I would put a set of 653's on my car without giving it another thought. I attached a pic of the correct lenses, as far as fog. I hope I have answered your question.
