Will these work with my factory wiring harness?

These use standard OEM connector design. Plug them straight into your existing harness — no rewiring or adapters needed.

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

You'll have better access with the bumper off, but it's not mandatory. Factory mounting points are accessible from behind the headlight opening. Work in good light and use basic hand tools.

What about the bulbs — are those included?

Assemblies ship empty. Source your bulbs separately to match your preferred wattage and type (HID, LED, or halogen options available aftermarket).
