I was interested in these as well. I already have aftermarket 6K HID's........I suppose it wouldn't hurt to upgrade the fogs too. For $100.00 a pair they seem too good to be true - the factory foglight assemblies for our cars are $205.00 each! My only concern is that they'll look tacky. Not the light output but the assembly itself that is. Alot of aftermarket headlights from companies like Depo kind of look cheap and ricey and that's what i'm afraid of with the fogs from Blinglights. Their website doesn't show a picture of a Crossfire with the lights off so i'm not sure what the assembly looks like. If it looked purely OEM then it would be a no brainer to upgrade to them for a mere $100.00.
