I bought the black housing option and installed these on a 2006 Dodge Durango SLT 4x4 (4.7L V8).The assemblies included running lights, but not head lamps. No big deal, I was able to remove the existing lamps from the old assemblies and they fit perfectly in the new assemblies.Installation was easy - the hardest part was removing the old assemblies. Once those were out, these new ones popped right in. Tightened up the screws, peeled off the protective wrap on the lenses, and moved on to checking alignment.The assemblies needed no adjustment. I did the whole "25ft. out and 1-2in. lower than lamps center point" check, and these new assemblies were exactly where my old assemblies taped out.These crystal clear lenses made for a significant improvement in visibility, and the black housing looks great!(side note: 2006 Durango parts seem difficult to find. I broke one of the brittle plastic retention ball clips when removing the old assemblies. Can't find them anywhere. I was even considering a custom fab with a 3D printer, but figured I'd try the new assembly without the ball clip support. The three remaining screws seem to hold the assembly just fine without the ball clip, so for now I'm going without it. ymmv)
