Will this install without removing the front bumper or grille?

No, you'll need to remove the bumper fascia to access the mounting hardware behind it. Plan on 30–45 minutes for the job with basic hand tools. Once the fascia is off, the headlight pulls straight out and the new unit bolts directly into the factory points.

Does this come with a bulb?

The assembly itself ships without a bulb. You'll need a standard H11 halogen bulb, which you can source separately or transfer from your old headlight if it's still good.

Will I need to re-aim this after installation?

Yes. Even though this uses factory mounting points, a quick vertical and horizontal adjustment at the rear of the assembly is smart to ensure your beam pattern isn't aimed too high or low. Takes five minutes with a Phillips screwdriver and a wall or garage door.
