Do these bolt directly to factory mounting points or do I need to modify the bumper?

They mount at factory rocker points — no drilling or cutting needed. Test-fit first to confirm clearance before final installation.

Will I need to run new wiring or can I tap into the existing side marker circuits?

These are designed as direct replacements, so they connect to your factory side marker harness. If the original connector is damaged, you may need to splice or source an adapter.

Do the lenses require any prep before install, or do they come ready to mount?

They arrive brand new and ready to go. Wipe the mounting surface and lens with a clean cloth before installation to ensure proper fit and light output.
