Cap Headlight Brightness Nationwide

U.S. motor‑vehicle safety standards should be updated to set explicit, technology‑neutral upper bounds on luminous intensity for headlamps (including LEDs and laser‑based optics), require periodic alignment checks at state inspections, and ban sale/use of aftermarket headlamps that exceed those caps for on‑road use. This closes the old Standard 108 loopholes manufacturers exploit and creates clear enforcement paths for NHTSA and states. — Updating headlamp regulation addresses a concrete, high‑frequency public‑safety harm and is a straightforward policy lever that binds manufacturers, protects drivers and pedestrians, and illustrates how device‑level tech advances outpace governance.
