Do these use the factory bulb sockets?

These assemblies are designed as complete units. Confirm bulb compatibility with your vehicle's existing wiring before final purchase to avoid unexpected adapter needs at install time.

What mounting hardware comes with these?

The assemblies use factory mounting points. You'll need to verify what fasteners are already at those points on your vehicle — some may require backing plates or shims depending on condition.

Does the chrome housing need any prep work before install?

Chrome finish arrives ready to bolt on. No painting or primer needed. Once mounted, sealed connections protect the interior optics from moisture.
