I want to change my fog bulbs to a white bulb to replace ones I was having problem with. I want a white-appearing bulb that is as bright as the stock halogens. I gotta say, I switched back to the 55w stock halogens and notice quite a difference-the amber stock fogs light up the night much better than what I was using. (I was using a blue-coated 85w bulb that appeared white, but fizzled out-if interested scroll down for post).
