This flashing stop sign has DG reflective sheeting. The illuminated sign (R1-1) conforms to the specifications of the Federal Highway Administration (FHWA) as set forth by the MUTCD. The innovative LED technology employs a set of synchronized high intensity LEDs. The LEDs extend the range of visibility of the sign during both day and night and in all weather conditions. The addition of flashing LEDs also increases driver awareness for added safety.
