Will these plug directly into my truck's factory wiring harness?

These are designed as direct-fit assemblies for your model year. Test-fit before final installation to confirm plug compatibility with your specific truck's electrical connectors.

Do the bulbs come installed or do I need to source them separately?

The LED projector units are pre-assembled. Confirm bulb type matches your truck's harness before installation — some factory connectors may require an adapter depending on your year's configuration.

Can I install these myself with basic hand tools?

Headlight swap typically requires removing the front fascia or grille section and unbolting the original assembly. Grab your service manual for torque specs and fastener locations — the actual swap is straightforward once you access the mounting points.
