HID headlight housings for Mazdaspeed3?

Sorry if I missed a thread about this but I couldn't find any answers yet. I have a 2012 Mazdaspeed3 tech package which comes with HID headlights and I can't find any aftermarket headlight housings/assemblies that fit with stock HID. If you could point me to a website that sells them that would be awesome.

Thanks in advance!
