Philips Hi-Visibility bulbs offer more light output, but don't have any blue coating on the bulb (this coating cuts down on light output, and causes them to run hotter temps ). They're also not $20 a bulb..
Many people on this board have had short life issues with Silverstars. I've done side by side comparisons in my own vehicle, withh a standard bulb, and a silverstar. Headlights were properly aimed, in a driveway, on a garage door, and on the road there was no difference in performance. The philips had more light, and so far have been great. I've had them 1 year now.
