Does this mount using factory attachment points?

Yes. This assembly mounts at factory locations with no drilling or bracket work. If your vehicle's mounting hardware is stripped or corroded, you may need replacement bolts — check them before assembly.

Do I need to buy a bulb separately?

The bulb is not included with this assembly. You'll use your existing bulb or source a replacement separately — bulb type is listed in your owner's manual.

Can I install this myself with basic hand tools?

Installation is straightforward — disconnect the electrical connector, remove the mounting bolts, and swap in the new assembly. You'll need a socket set and a screwdriver. If you've never done it, a shop can handle it in under an hour.
