The "Cool Blue" 9007 bulbs don't do anything to help the apparently poorly designed lights on my 2000 Grand Caravan, so I've been reading all I can here and on Daniel Stern's site. It looks like the GE Night Hawk is the best bulb for the money for my needs, but I am bothered by the bulb life rating with is only 250 hours. That would be only a few months of winter driving. Do these bulbs typically last much longer than their rating hours?
