Do these use my factory bulbs?

These accept your existing OEM bulbs—no new bulbs needed. Simply swap your current bulbs into the new housings.

Will I need new wiring or connectors?

Factory connectors fit without modification. If your truck is stock, plug them straight in. If your wiring harness has been customized, test-fit before final installation.

What about beam alignment after install?

These mount at factory rocker points—alignment should match your original headlights. If you notice significant drift, have your headlights aimed at a shop with a headlight aimer for a quick adjustment.
