Do these headlights plug directly into my stock wiring harness?

Yes, they're designed for OEM fitment on stock xenon models. Your factory connectors should mate directly — no adapter harness required.

What happens if one LED ring burns out later?

Individual bulbs can typically be replaced, but verify compatibility with your exact assembly before ordering replacements. Refer to the manual or contact support with your VIN for part-specific guidance.

Do I need to adjust anything after installation?

The auto-leveling system handles beam adjustment automatically during normal driving. Once mounted, the headlights should self-calibrate within the first few driving cycles.
