if you get a set of denali lights there are few guys making adapters to bolt these right in. got mine waiting on paint in the housings and the rest of the denali swap. All the projector headlights are for halogen and would probably have less output then your factory headlights with hids. I am assuming your looking to do hids if you want projectors.
old thread but, Can you just swap the denali headlights into a non denali sierra?
