Re: fog lights.
Depends on what you want. I have seen factory fogs with Nokia Hyper yellow bulbs. HID retro fits. PIAA swaps. Driving beam swaps. I have not seen anybody front the cash and do a Hella 90mm Bi-Halogen or Bi-Xenon conversion yet though. Personally, I'm investigating that Bi-Halogen version myself. Some folks make 4 inch LED lights now too. Lots of options really.
