          Very bright

          I got these for my Raxiom Chrome Projector Dual CCFL Halo headlights and these things are super bright. Make it look daytime outside!

          Upgrade to Sylvania Silverstar H1

          I loved my upgraded projector headlights for the looks, but they were terrible for driving visibility...until I found the new Sylvania Silverstar H1 replacements. The difference was astounding. I can see again. I am so glad I took the advice of the salesman at AmericanMuscle. I could not be happier.

          Sylvania Silverstar

          The light output was no different than that of stock bulbs. Used in Raxiom projector headlights.

          Not much of an upgrade at all

          I bought these for the Raxiom chrome headlights for my 2009 GT California Special, and am sorely disappointed. The clarity of the light isn't anything above a normal headlight at all, and now after buying them I am already searching for a whiter high intensity light.

          Solid Lights

          Good price, and way brighter then stock. Bought them when I got the Raxiom smoked lights and they work perfect.

          Good quality and bright! These bulbs are great quality for the price! Put these in and it adds an intensity to the look of them without being blinded

          Great looking lights

          These bulbs really provide a different from stock look without making your beloved 'Stang look like another import racer cruisin' the streets. Keep in mind these bulbs provide bright, WHITE light. Do not purchase if you are looking for an ice blue headlight. Provides great visibility, a distinct look, and when paired with projector lamps, a significantly safer beam pattern...Another great product offered by American Muscle!

          Sylvania Angel Eye Headlights

          These headlights are amazing. It only took me about half an hour to install, I had no previous car experience at all. They, make my 1999 Mustang look so much better, I recommend them to anyone looking to improve night time driving vision and the overall look of the front of your Mustang.

          great light bulbs

          These lightbulbs may not be the top of the line but they are great. They light everything up nice and bright. THe only other bulbs that would be brighter are the HID bulbs which unfortunately are not allowed to be used with the Dual Halo Projector lights I have now.

          These bulbs were nothing like what I expected. I was expecting them to light up the night sky when I turned them on, not. I honestly can't notice much (emphasis on much, obviously theres a difference, just not much of a difference) of a difference between these and a brand new set of regular bulbs. At $20 a piece, you'd think they were incredible. Also, on the back of the actual packaging, it says that the life of these bulbs is 1/5 (like 1 star out of 5). I am not saying these are low quality bulbs, but come on.
