Trailer Mount Solution

The PM P521 T Overwatch LE Speed Display Trailer has a 18″ tall character display and when in full operating position, stands over 8 feet tall. The speed display sign folds down creating a low trailer profile for easy transport and storage. Standard features include high & low speed blanking, flashing digit violator alert and traffic management arrows.

Optional features include our violator alert system (a flashing strip of red and blue LED’s and/or the distinct “SLOW DOWN” message in red LED’s) when approaching vehicles do not slow to the selected speed. Also available is our Overwatch LE ALPR Package, which records the time, date and speed of oncoming vehicles without the use of cumbersome pneumatic tubes placed across the street! Please see the reverse for complete details
