          Great Visibility

          My mustang had some standard bulbs. They just weren't bright enough. I decided to brighten up the night with these Sylvania Silverstar Light Bulbs. Great Visibility!

          light shines great

          This light really shines brighter than stock but i was expecting it to look like hid's but still makes you car look great at night. The light shines really white and far.

          Very easy install! Much brighter than OEM quality. Also makes for a better view when you add some new aftermarket headlights!! Easier than HID install!

          Sylvania Bulbs

          Every Dox Mustang Needs These

          Fox Mustangs need all the help they can get in the lighting department. I'm on my third set of Silverstar bulbs on my '90 Mustang and I can say they're well worth the money over standard bulbs. They put out a much brighter, whiter light and you can easily notice the difference compared to regular bulbs. They also put out an attractive shade of light with no bluish or yellow tint, just pure white light. I run these in my other vehicles as well but they're especially beneficial for older cars like Fox Mustangs.

          Bright Lights

          I purchased these along with my new headlight kit. These bulbs are much brighter then the stock phillips bulbs that came with the kit. I have had them before on other cars and I strongly suggest the Silverstar bulbs to anyone who is replacing their lights.

          Sylvania 99-04 lights

          Recently purchased a set of smoked headlights for my car. Made it look absolutely awesome, but the stock bulbs werent able to fight with the tint. So, I got theses and, wow, its like they werent even smoked. Works great!!!
