The present invention provides an attachment installed unobstructively on a visor about a lens of a traffic signal and configured to receive a preemptive signal from an emergency or other authoritative source and transmit a correlating message visually or audibly to a surrounding citizenry via a display and optionally a speaker. The attachment can include one of a variety of display means to animatedly or statically communicate a directive to the citizenry. An optional series of LEDs can be included to draw attention to the directive as displayed. The directive can communicate an action to be taken by the citizenry, the type of vehicle approaching, or a route to be followed. Optionally, the frame or display may be shaped at least in part similarly to a standard street sign. The attachment provides a way to quickly and clearly direct people in a manner that clears a path for authorities.
