Need some advice and help. I changed my rear lights to LED. No major problem. There was some confusion on the bulb numbers but I finally figured it out. I have a 2019 Big Horn Cummins. Do I have projector headlights? I look at them and there is a small rectangular looking plastic gizmo just ahead of the lens. From what I understand this should mean I have projectors. Can they be changed to LED's. Looking on line I am assuming I can. My local body shop told me he would change them for $65.00 labor. Does anyone have experience with any brand of CanBus connectors that they would recommend ? I see various customer ratings that rate most average and the rest really bad?
