Does this come with the bulb?

The assembly itself is included; check your owner's manual for the correct bulb type and purchase separately if needed. Most halogen bulbs are inexpensive and widely available.

Will I need new hardware to mount this?

This assembly mounts at factory locations using OEM fastening points — your existing hardware should work. Test-fit before final tightening to ensure proper alignment.

Can I paint or modify the housing?

The housing is hard panel construction designed to work as-is. Any painting or modification should be done carefully to avoid damaging the internal optics and reflectors.
