http://www.xenonlink.com/ very good prices, works very well. Extremely simple to install, all plug and play. just get the kit for whatever bulb you car takes. if its a 9005 halogen bulb get the 9005 kit and your old connector plugs into the HID balist and then you just mountthe balist up and plug in the new HID bulb to your lens
i have some dark tint in the back so i dont mind have people with HIDS behind me 8]
