Unlike the old-fashioned signs with pre-drilled holes and static LED output, TruSign Speed Indication Devices are the modern, flexible and friendly face of speed compliance. They are lightweight enough to be relocated from site to site by one person alone, and their energy efficiency means that a small solar panel is all you need in order to go completely off grid for low cost and easy installation. Data logging comes as standard with the TruSign 30CR, our most popular unit. As each sign is effectively a low resolution LED matrix screen; it is entirely possible to have a range of output messages such as TOO FAST, SLOW DOWN, Smiley, Frown, vehicle speed and so on. It is even possible to automatically adjust the speed activation threshold from, say, 30mph down to 20mph during drop-off and pick-up times outside a school.
