Do these plug into the factory harness?

Yes, these mount to factory points and wire into the existing fog light harness. No rewiring required if your CR-V came equipped with factory fogs.

Will I need to remove the front bumper to install these?

Removal is the cleanest approach for proper fitment and wiring access, but mounting method varies by installation approach. Bench-test fitment first to confirm your preferred install path.

Are bulbs included with the assembly?

Bulbs are not included. Verify your CR-V's OEM bulb specification before ordering replacements.
