Do these mount at factory rocker points or do I need to drill?

These mount at factory attachment points — no drilling or fabrication required. Test-fit before final installation to confirm alignment with your specific vehicle.

Will these lights work with the factory wiring harness?

The assemblies are designed for direct fit, but bulb socket compatibility and wiring integration depend on your vehicle's original harness configuration. Have a wiring diagram handy before you start.

Do I need to prime or paint these before installing?

They arrive ready to install as-is. If you want to match body color or customize the finish, prep and paint before mounting to avoid masking existing trim.
