Do I need a bulb for this headlight?

Bulb is not included. You'll need to transfer your existing bulb from the old assembly or source a replacement separately — check your owner's manual for the correct bulb type.

Will this mount directly to my car without any brackets or adapters?

Yes. This assembly mounts at the factory attachment points with no modification needed.

Can I paint this headlight housing if I want a custom finish?

The hard panel construction can be prepped and painted, but test-fit the assembly first to ensure alignment before committing to any finish work.
