Will these work with my factory wiring harness?

These mount at factory points and are engineered for OEM connector compatibility. Test-fit before final installation to confirm plug alignment with your vehicle's existing harness.

Do I need to prep or paint these before install?

These ship with chrome housings ready to bolt on — no painting or prep work needed. If you prefer a matte or custom finish, light sanding and standard automotive paint will adhere to the housing.

Are bulbs included in the headlight assembly?

Bulb configuration not specified with this assembly. Plan to source HID or halogen bulbs separately to match your preference and local regulations.
