+1 for zXe's. I've got them in my fogs and BOY are they bright. They're a really nice white too. I'd recommend them. I just got some Philips X-treme Power headlights off of Amazon for 38 bucks shipped... which is like half the price of the zXe's. Them's expensive.
And believe it or not, I JUST had my right headlight (silverstar) go out... after almost 3 years. And yes, I drive it daily, yes, half of my commute (or sometimes all of it) is during dark hours. I think I just got a really good pair maybe?
