Getting your message across is vital in many situations, but none as important as warning drivers of people working on the road or along the roadside. The Ring-Co RD² (Rapid Deployment Display) is a state of the art LED message board that assembles in less than a minute, giving clear, easily seen directives to drivers and pedestrians. The RD² could play a role in saving the lives of emergency responders, and the men and women who put their lives at risk working roadside for electric, phone, and tree-trimming companies, to name a few. This versatile tool can also be utilized in crowd situations, giving directions or other important information. Wireless control is another aspect of what makes this sign… significant.
