Do these come with bulbs?

Bulbs are not included with these assemblies. Your existing bulbs should transfer over — verify the type before ordering if you need replacements.

What hardware do I need to install them?

These mount at factory attachment points, so you'll use your original fasteners. If any clips or brackets are broken or missing, have those on hand before starting.

Are these sealed against moisture?

Installation method and seal integrity specs are not detailed — test-fit before final assembly to confirm fit and check for any gaps around the lens.
