Do these come with bulbs, or do I need to source them separately?

These assemblies come with the LED DRL module integrated. If your truck currently uses halogen low beams, you'll keep those or upgrade separately—the DRLs are independent of your main beam setup.

Will I need to do any wiring, or is it plug-and-play?

Mounting is plug-and-play at the factory connection points. DRL operation depends on your truck's existing wiring harness—some trucks activate DRLs automatically, others require a small relay or module. Test-fit first to confirm your truck's compatibility.

Can I install these myself with basic hand tools?

Yes. You'll need a screwdriver and socket set to remove the old housings and bolt these in. The entire swap takes under an hour if you're comfortable working under the hood. Follow your truck's service manual for torque specs on the mounting fasteners.
