Want incredibly bright, white headlights? This HID Bi-Xenon conversion kit will transform your nighttime driving! It's designed for vehicles that use H4/9003 bulbs, giving you both high and low beam function from a single bulb (that's what 'Bi-Xenon' means). The kit includes everything you need: 2 HID bulbs, 2 digital 55W AC ballasts, and all necessary wiring. You can choose your color temperature, from a pure white 4000K up to a cool blue 12000K. It's a 12V system, brand new in the box, with a 1-year warranty. Please note: this is a performance/custom fitment kit, not a direct plug-and-play for all cars, and HID kits must be installed properly with projectors to avoid blinding other drivers and to be legal in many areas. Check your local regulations! Made in China. If you're looking for a massive upgrade in light output and a modern look, and you're willing to do the install right, this kit delivers serious performance. See the road like never before!
