Do these plug into my factory electrical connectors?

These units mount at factory attachment points and are designed for bolt-in installation. Verify your vehicle's connector type before ordering — adapter harnesses are available separately if your wiring differs from the housing design.

Will I need to adjust the beam after installation?

Once mounted at the factory points, projector headlights typically track true. If you notice beam height or aim issues after install, most housings include adjustable mounting brackets — check your specific unit's hardware for adjustment provisions.

Are bulbs included, or do I supply my own?

Bulbs are sold separately. Confirm your vehicle's headlight bulb type (H11, 9005, etc.) before purchase — the projector housing will specify which bulb it accepts, and you'll install them into the unit during final assembly.
