Do these bolt directly to the truck without modification?

Yes. These are designed for factory mounting points — no drilling, cutting, or welding required. Standard hand tools and your service manual are all you need for install.

Do these come with bulbs and wiring harnesses?

The assemblies ship as housings only. You'll reuse your existing bulbs and harness connections from the original lights.

Can I paint the black housing a different color?

The housings arrive finished. If you want a custom color match, light sanding and standard automotive primer and paint will work — test on a small area first to confirm adhesion to the housing material.
