Do these plug directly into my factory wiring harness?

These are designed as direct-fit units for your vehicle's mounting points. Verify connector compatibility with your specific model before purchase—some years may require adapter harnesses depending on your truck's original equipment.

Will these work if my truck still has halogen headlights?

Yes. These are self-contained LED units that mount in place of your OEM headlights. No additional components or rewiring is needed beyond what comes in the box.

Are these street legal?

Street legality depends on your state and local regulations. Check your local DOT requirements before installation—some jurisdictions have specific rules around aftermarket lighting. Your service manual or local DMV can clarify what's permitted in your area.
