I have searched around and from what I read in order to do the 2010 headlight upgrade you need the headlights, wiring harness, computers, and Sam module in order for the lights to be fully functional meaning knight vision and all smart features to work. I was wondering if the 2010 lights directly bolt in to the 2009 body and plug in no problem. Also if I get the headlights will the regular headlamp light still work temporarily without all the other features
