2011 Tahoe. Just removed and replaced both headlight assemblies. Got them on Amazon, brand Amerilite, for $123 for the pair. They came with wires and halogen bulbs and plugs installed. All you have to do is undo 3 bolts on the assemblies and to get to one you have to take out 2 fender well bolts and 3 nylon push button clips to get old ones out and have enough room to wiggle it out and wiggle the new ones in. Took one hour from start to finish. We'll worth it, huge appearance and brightness upgrades.
