Do these lights require any cutting or modification to the bumper?

Mount at factory fog light mounting points—no cutting or drilling needed. Test-fit before final installation to ensure proper alignment.

Does the switch wiring tie into the factory electrical system?

The harness is designed to integrate with the vehicle's existing wiring. You'll want to trace the factory fog light circuit or have an installer confirm the connection point specific to your vehicle's configuration.

Are these lamps street-legal?

These are manufactured as replacement fog lights. Check your local regulations before installation, as fog light legality varies by region.
