selling my 9000 so I took out my HID's. they were only used for about 3 weeks before I crashed the car. They work flawlessly and are top of the line. MobileHID is where they're from and if you do some research you will find that these are the most user friendly and durable HID's on the market. The Ballast is plug & play and both water resistant and shock resistant. I'm asking $120 or best offer.
