The Fast 1000 Radar Speed Display Trailer is a heavy duty product designed for continuous use. The 18” tall full matrix characters are created with high intensity LED’s and their brightness adjusts to the outside light for maximum viewing day or night. Custom built with top quality, many optional features may also be added, including data recording, electric leveling jacks and our featured “Hey, Slow Down” lights. These flashing red and blue LED’s turn on when the oncoming vehicle does not slow to the posted speed limit. It’s just a reminder of the consequence for speeding when law enforcement officers may be near.
