HID Headlights

Hey everyone. I'm new to the Buick forum and had a question about the headlights. I have a 2013 Buick LaCrosse with the standard halogen headlights, and am looking to upgrade them to the OEM HID articulating headlights. Is this at all possible? I would assume there might need to be some changes with the wiring, the computer probably needs a flash, and who knows if the BCM is going to accept them. I did see an empty fuse slot for the HIDs, but didn't look yet to see if it is wired up or not.

Has anyone tried this before or has at least looked into it? I would have liked to had the HIDs, but I got such a great deal on this model LaCrosse (Premium I) that I couldn't pass it up.

Thanks in advance!
