Do these mount using factory attachment points?

Yes. These are designed for factory mounting points — no drilling or frame modification required. They bolt directly into place using your vehicle's existing hardware.

Do bulbs come with these housings?

Bulbs are not included. You'll transfer your existing bulbs from the factory housings or source replacements separately.

Can I install these myself with basic tools?

Installation requires disconnecting the factory housings and fastening these in place — standard hand tools and maybe a socket set. If you've done basic bolt-on work before, you can handle it.
