Fast-275 Radar Speed Display Sign

Data packages and accessories are sold separately

This radar speed display sign has your pole mount traffic calming needs covered with our Fast-275 pole mount radar speed signs. Mounted permanently or semi-permanently, these high intensity LED displays get the attention of oncoming drivers. The speed radar signs 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 12″ characters. The 12″ character is appropriate for slower speeds (sub 35 MPH) and is readable to 750 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.
