I just installed the SilverStar high Beam and Low Beam bulbs this afternoon and it took no more then 10 minutes for all 4 bulbs to be removed and the new ones put in their place. I can't wait to see how they look tonight. tomorrow I think I will pick up the silverStar fog light bulbs and upgrade the stock bulbs. Because of the instructions on this site it made the replacement a snap. I only removed one screw to get to each of the low beams and the high beams was even easier to get to.
