Do these plug into my factory wiring harness?

Yes — these are designed to connect at the factory connector points. No rewiring needed; the sequential function is built into the housing electronics.

Will I need to adjust alignment after install?

Plan on a headlight aim check after installation. Use a flat wall or headlight aiming tool to confirm beam height and horizontal level match your previous setup.

What's the warranty on these?

Return process and coverage terms are handled at checkout. Review your order confirmation for warranty details specific to your purchase.
