If your going to go HIDs, please either do a projecter lamp conversion or a lens made for the HID. If not you will just scatteryour HID light everywhere, just like those pesky ricers and then oncoming traffic will really hate you. A properly setup HID/projector setup will have very crisp light cutoff to keep the light where its supposed to go.
