variable message sign

Engineers at I-ROAD Technologies have designed various forms of mobile variable message signs that use solar power and batteries as the power supply system. They are very suitable for temporary traffic management and road construction operations. The structure of the solar-powered mobile variable message sign includes a tire chassis, a base for placing batteries, a manually adjustable support pole, a remotely controlled LED information screen, and a solar panel. The height can be adjusted as needed, usually up to 12 feet, and can be customized and developed according to customer requirements.
