Will I need to remove the front bumper to install this?

Depends on your comfort level. Most installs access the headlight from inside the engine bay without bumper removal, but pulling the bumper gives you more room to work. Check your service manual for your specific approach.

Does the bulb come with it?

Assembly only — you'll transfer your existing bulb or source a replacement separately. Make sure it matches the OEM bulb type for your model year.

Is any painting or prep needed before installation?

Not on your end. This arrives ready to mount. If the housing gets damaged during shipping, contact support for a replacement — do not attempt to repair the housing yourself.
