2008 GL450 Halogen headlight housing to Xenon headlight Housing?
Recently I found a pair of OEM 2008 Xenon headlight lamp with self leveling feature headlight housing for the GL.
I was wondering is this a drop in and plug? or I need to go to dealer have them activate the self leveling program in the car computer?
Any comments or suggestions will be greatly appreciated
Thank you




I have a pair too but never installed them.
