They aren't the exact same bulbs. The factory headlights use an H11 low beam and a 9005 high beam, while the ANZOs use H7s for both high and low beams. They are halogens, so overall output isn't that much better than stock, but you tend to get more range (though less intensity) with the ANZO's projectors. If you want to improve output, you'll probably need to jump into an H7 LED conversion kit. We generally recommend the CrystaLux G11 Series H7 with these headlights.
