Does this come with the bulb and wiring harness?

The assembly ships as a housing only. You'll reuse your existing bulb and connector from the OEM unit you're replacing—no new wiring needed.

Will I need to adjust aim after installation?

Since this is factory-spec geometry, aim should fall close to OEM. A quick headlight alignment check after install is smart practice, but major adjustment is unlikely.

What if I ordered the wrong side by mistake?

Check our return policy on the checkout page. Verify left vs. right before finalizing—left is driver's side on imports and passenger side on domestic trucks.
