Hello all. I just purchased a pair of Philips Vision Plus H4 bulbs for my stock headlights on my '87 300E. Has anybody else tried these bulbs? I'm just trying to get an idea if there will be any type of improvement over my stock bulbs. They claim up to 50% more light (http://www.powerbulbs.com/pvph4.htm
) and I remember reading somewhere that these bulbs aren't DOT approved, but I'm not sure. Any experience with these would be appreciated.
