Our Bulbs are engineered to last a lifetime. They look excellent, they run cool, and they last. These bulbs are popular for a reason. Our Kits are built with High Quality Philips ZES that put out an amazing 6000K color temperature that is absolutely perfect for looks and visibility. Our lights put out 10000 lumens each for excellent visibility, while maintaining your factory beam pattern so you are not annoying the other drivers. Compare this to your factory halogens that put out 1200 lumens. These are over 3X brighter! These are designed in aircraft grade CNC machined housings that are engineered right, so there is a perfect beam with no light scatter. Our "Platinum Head Design" at the tip of our lights works in relationship with the panels to create a "laser light source" that illuminates further, with stronger penetration and a more defined beam pattern. In addition, we made our sets with the slimmest design on the market so fitment is never an issue. The clearance is about the same as most of the factory bulbs that you are removing so there is no chance of incorrect fitment. Most competitors use bulky cooling units at the back that have a hard time fitting in most assemblies. Our unique aluminum fin radiators encourages optimum cooling of our units so they can last a lifetime. Our bulbs are designed with direct fit plug and play connectors that require no wiring. These will simply plug-in to your factory connector and replace your factory bulbs with no modifications required. This makes installation a breeze.
