Will this bolt up to my factory brackets without any modification?

Yes. This assembly mounts at the factory rocker points with no drilling or adapter plates needed. The electrical connector is OEM spec, so it plugs directly into your existing harness.

Does the bulb come with this headlight?

Bulb is not included. You'll need a replacement bulb cartridge that matches your original—pull the old one out first to confirm the type.

Can I install this myself, or do I need a shop?

This is a straightforward swap. Unbolt the old unit, disconnect the harness, reverse the steps with the new assembly, and test your lights before closing everything up. Basic hand tools and maybe 20 minutes of your time.
