Do these come with HID bulbs installed?

The headlight assemblies themselves are included, but confirm bulb inclusion with your order details. Most buyers source HID bulbs separately to match their desired color temperature and wattage.

Will these connect to my factory wiring harness?

These mount at factory attachment points, but electrical compatibility depends on your vehicle's existing harness. Test-fit the connectors before final installation to avoid surprises.

Is any prep work needed before installation?

No painting or modification is needed — these bolt straight in using factory mounting holes. Remove the old headlights, disconnect the harness, and swap in the new units.
