Will this bolt straight to my vehicle without modification?

Yes. This light mounts at factory attachment points — no drilling, no brackets, no adaptation needed. Install takes minutes with basic hand tools.

Do I need to replace the factory wiring harness?

The existing brake light harness connects directly to this assembly. If your factory connector is corroded or damaged, address that first — the light itself uses the stock electrical setup.

Is this street-legal?

LED 3rd brake lights are legal on most roads when they meet brightness and color standards. Your vehicle's existing brake system compliance carries over — this is a direct swap replacement, not a modification to the brake circuit itself.
