Do these use the same bulbs as my factory headlights?

These are designed with LED reflector inserts, so bulb compatibility differs from stock halogen units. Confirm your bulb type before installation to avoid ordering the wrong size.

Will I need to wire anything, or is it a straight plug-and-play swap?

They're built to use your truck's factory electrical connectors and mounting points. Once you remove the old headlights and bolt these in, the wiring should connect without modification.

Do the black housings need to be sealed after installation?

Test-fit them first to confirm the seal is intact around the housing edges. If you see gaps, apply weatherproof sealant around the perimeter before fully securing them to prevent moisture inside.
