he means the chrome as opposed to dark grey housings I think, like 99-00 mustangs came with
There was a guy selling his sonic blue car a few months back with clear headlights. You might do a search in the for sale section.
On my SM, the clear headlights look great. Some of us aren't fans of that whole smoked/tinted/blacked-out thing. The '99 headlights actually go quite well and project a bit more light, so don't be afraid to try them if you can score a nice set. New from Ford, they are double the price of the smoked-lens housings.
I think I got these from Pro Tuning Lab for about $100. I just threw some extra silicone on them for any condensation potential they might of had. They look great and really changed the front end. I didn't mind the yellow Sidemarkers, but the lights that were on the car were in terrible shape so I opted for these.
I was searching the net for Sonic Blue Cobras (I can't help it I'm addicted) and came across the car.
