So I got this 2007 CTs not to long ago, and when I went to change the bulb I realized it has HID bulbs in the low beam but not the high beam. I'm trying to figure out if these are HID protector assemblies or the factory headlight assembly. I attached a picture. How can I identify what type of assembly they are? And if they are factory assemblies, how can I change the HIDs back to halogen? Or should I just buy new projector assemblies? Really confused by this so I would appreciate any help.
