I dont think you can get them from their website.
Umnitza has them and I think m3motorwerkes has them. It's a replacement for the entire US headlight assembly.
I think there's a PnP adapter for like 30$ that allows you to just plug them right into the regular wiring harness, but I'm not sure if that's if you got the DDE (angel eyes) or not.
Either way, you want a ZKW elipsoid projector headlight. HID retrofit with the ZKW's would be even better. Angel eyes are cosmetic, mainly (partialy an other car visability factor)
Just for the elipsoid headlights, it's like $350-$400.
