Hi, You cant just swap them.. You need to have ballasts in order to use HID bulbs. If your looking to get just Hyper White halogen bulbs go with Sylvania Silver Stars.
If you want to retrofit a set of HID bulbs into your housings, I can set you up with some necessary parts, you wil need 2 Ballasts, 2 HID Bulbs, and Somone thats god with retrofitting bulb sockets. Contact me VIA PM for more info.
