Fast-475 Radar Speed Display Sign

The latest entry in pole mount radar signs is the Fast-475, a combination digital display crowned with a medium density LED matrix graphic display. Capable of not only showing oncoming vehicles their speed but also of acting as a Variable Speed Limit sign or a two line Variable Message Sign. Individual LED control provides animation capabilities not found in other radar speed signs. Like all of our signs, the Fast-475 can be directly hard-wired to your electric service or optionally powered by a solar panel power system.

Each of these designs feature a full matrix high intensity LED display with 18″ characters. The 18″ character is appropriate for higher speeds (35 MPH+) and is readable to 1250 feet. In addition to the standard flashing digit Violator Alert, several additional Violator Alerts are available including an embedded “SLOW” message and our flashing Red/Blue bars, particularly effective at night. The two character rows onture full 9″ characters for legibility about 500 feet downrange.
