After over two years, one my Philips VisionPlus headlight bulbs finally died out. I was very happy with them so I decided to go Philips again, this time the Philips X-treme Power. It’s got the same attributes as the VisionPlus except this one offers not just 50% but 80% more light than stock bulbs. This, again, without requiring new wires and ceramic sockets. Installation was easy as usual and it was bright. I can’t say really say for sure that it’s 80% brighter than stock but it sure is as brighter than the VisionPlus.
