Bavauto isn't a great place for headlights. You want ZKW, those are OEM. Bavauto sells inpro headlights, if I'm not mistaken. They'l do the job, but they still arn't as good as ZKW's. Umniza
carries the ZKW's and has some nice DDE packages if you want as well. Bavauto is mostly aftermarket.
Once you get the ZKW's, get two HID retrofit ballststs, some HID bulbs, and some time and wire it all up.
