These costs vary depending on your year model, where you’re located and other things like CAPA certification, SAE compliance, warranty period, quality of materials, finish, and whether the assembly comes with or without bulbs or even a wiring harness. The halogen assembly is generally on the lower end of the price range while the Xenon assembly is on the higher end.
