I replaced the stock bulbs in my 2002 GC with SilverStars, and really like them. My headlights are 9007's, which are easy to find, but the fogs are something called a 9040, which is only about 40w, and are really hard to find. Sylvania doesn't make a SS in that size, but the 9005 is an exact fit in the fogs instead. They're about 70w, but so far I haven't had any electrical problems. Plus, they look great!
