Light Duty (LD)


These portable traffic signals are perfect for single lane closures and basic intersections.

The LD is optimized to control a single lane closure, but it is capable of far more. Its arm is 9’ long, meeting the MUTCD requirements. With the LD, you can quickly have two 12” ITE approved signals in positions mandated by the MUTCD at the mere push of a button. It is light enough that you can tow it with a pickup truck. Because it is only 6’ wide (the narrowest in the industry), you can fit it in almost anywhere. The LD features our exclusive Intelight ™ ATC controller running Maxtime™ software. Our control units communicate in real time via wireless, license-free, encrypted spread spectrum radio. The control system can easily handle 7 trailers, as well as complex phasing. It can even function as a knock-down. The LD comes standard with 300 watts of PV (adjustable on 2 axis) and 800 Ahr of AGM batteries.
