Will this fit without removing the bumper?

Mounting is at factory points, so you can access it from the engine bay. Bumper removal depends on your comfort level, but it's not required for bolt-on installation.

Do I need to buy the left side separately?

Yes—this is a right-side-only assembly. If you need both sides, add the left headlight to your cart.

Will I need to reprogram or adjust anything after installation?

Once bolted in, aim adjustment may be needed to match your previous headlight beam pattern. Refer to your vehicle's service manual for headlight adjustment steps.
