Do these connect to the factory fog light wiring harness?

These are designed as direct replacements for factory fog light assemblies. You'll connect them at the existing fog light connector under the bumper — no new wiring harness needed if your vehicle already has fog lights.

Will I need to adjust anything after installation?

LED projectors come pre-aimed from the factory. Once bolted in place, beam alignment is locked. If your bumper sits differently than stock, you may need to verify sight lines, but the lights themselves don't require adjustment.

What if the chrome housing gets damaged — can I replace just the bezel?

Assembly condition and replacement part availability depend on your supplier's return and warranty terms. Check your specific order before installation — some shops warranty the full assembly, others the internals separately. Contact support with your order number if damage occurs.
