Do these LED strips require separate wiring or do they integrate into the factory harness?

The LED strips are built into these housings. Confirm your wiring compatibility with the factory connector before installation — some builds may need an adapter or relay module depending on your electrical setup.

Will these fit and function with my existing headlight switch and high-beam control?

These are projector housings designed for direct bolt-in fitment. They use factory connectors, so switching and beam functions should operate normally once installed. Test both low and high beams immediately after to verify proper alignment.

Do I need to adjust aim after installation?

Yes. Projector headlights have adjustment screws built into the housing. Plan time for beam alignment after install — uneven aim reduces visibility and creates glare for oncoming traffic. A quick adjustment is worth the few extra minutes.
