Do these mount at the factory rocker points?

Yes. These are designed for factory mounting points with no drilling or bracket fabrication. Install with the existing hardware setup.

Will I need to prep or paint these before installation?

The housings ship with a finished black coating. Test-fit them first to confirm clearance and alignment—touch-up paint may be needed if the bumper has been reworked or has uneven gaps.

Do these lights come with bulbs?

Bulb configuration is not specified. Confirm bulb type and socket style before ordering to ensure compatibility with your vehicle's electrical harness.
