Do these covers work with my factory fog lights, or do I need to swap the entire assembly?

These are covers only — your existing fog light bulbs and housings stay in place. They bolt directly over the factory openings, so no rewiring or electrical work needed.

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

No. Access is from the front with the bumper on. You'll reach the mounting points from under the fascia. Plan 30–45 minutes per side with basic hand tools.

Can I repaint the black panels if I want a different color?

The black finish is paintable if you want to match a custom bumper or fascia color. Light sanding and primer prep before paint will give you the best adhesion.
