Will these mount to the factory fog light holes?

Yes. These mount at factory rocker points — no drilling or bumper modification needed. Line them up with the OEM cutouts and secure them down.

Does the switch plug straight into the dash?

The switch is included and ready to integrate with the factory wiring location. Confirm your vehicle's switch cavity matches this assembly before final commitment.

What if a bulb burns out after I install these?

H11 bulbs are common — any auto parts store carries them. Replacement is straightforward and takes a few minutes from under the bumper.
