Does this switch replace the factory dashboard button or add a new one?

This assembly includes its own dedicated switch. How it integrates into your existing dashboard layout depends on your wiring approach — some buyers tap it into the factory fog light circuit if one exists, others run independent power and grounds.

Will I need to cut or modify the bumper to mount these?

These are designed for factory mounting points, so no cutting is required. Test-fit the bezel against your bumper opening before final fastening to confirm alignment.

Can I paint the chrome bezel to match my bumper color?

Yes. Clean the chrome with mild soap and light scuffing, then prime and paint with standard automotive paint. Mask off the clear lens areas before painting.
