Do these lights need any wiring modifications?

These mount at factory points and use the factory connector. You plug them in where the originals connected — no rewiring required. If your truck's electrical is modified, test before final install.

Will these pass inspection with the smoked lenses?

The clear center lenses maintain visibility for brake and turn signals. Check your state's inspection standards — some regions have specific light transmission requirements for smoked housings.

Do I need to modify the body or fender to fit these?

No drilling or cutting — they bolt into the existing mounting points. Inspect your current tail light openings before ordering to confirm they're stock condition.
