Does this come with a bulb?

The bulb is not included. You'll need to source the correct bulb separately and install it into the socket before mounting the headlight.

Will I need any fasteners or hardware to install this?

It uses the factory mounting points on your vehicle. Check your existing hardware when you remove the old headlight — you may be able to reuse it, or pick up replacement bolts if needed.

Does this need paint or primer before installation?

It ships ready to install as-is. If you prefer a different finish, you can prep and paint before mounting — just test-fit it first to confirm clearance and alignment.
