I have a set of 55w yellow fog PIAAs (Plasma Ion/yellow) on my 03 sedan. They're not overly yellow, but they do a hell of job cutting through snow, mist, rain, etc. I'm more about the true performance of my mods rather than the "look".

yellow fogs!! pure sexyness

My old Lexus had yellow fogs. I miss it. I'm getting yellow fogs when I purchase bulbs for the projector headlights I'm ordering tomorrow.

Besides looking classy, it really does do a better job at cutting through the fog than halogen or white light.
