TEXT:

As a supplier to the U.S. Postal Service for lights, I have been asked about the legality of the High Mount Stop Light on the new Long-Life Vehicles. The only time this light comes on is when the driver steps on the brakes. Since the vehicle makes numerous stops, would it be legal for this light to flash and make drivers behind the vehicle more aware?

Thank you for a ruling on this request.
