Based on the Xoutpost options list, at the bottom it has 2001-2003 xenon, 04-06 adaptive bi. it states that for 04-06, the lense must state you have xenons, if not, they are halogen: (bottom of link)

My mother has an 04 without and I have an 06 with xenon; I have the stamping, she doesn't.

Do you have a picture of an 04+ with xenons without the stamping of adaptive? I would be very surprised if BMW added the complexity of two different adaptive bi-xenon housings, one with and one without stamping.
