I hope someone here can shed some light onto this for me. I have searched around, but could not find anything good. I have a 2010 1LT with the standard headlights. I found some of the projector style headlights from an LTZ on ebay that I am thinking about getting. I just wanted to know if anyone knew how much work was involved in getting those assemblies traded out. I am also guessing that the bulbs and wiring themselves are the same between the two, it is just a different lens design. Thanks in advance!
