Curve Warning & Guidance Systems (CWGS) are ideal for the most dangerous and accident-prone curves. CWGS are an array of LED BlinkerSign® signs activated by an approaching vehicle. Each of the wirelessly linked signs then continue to flash for a preset time to guide the driver through the curve. While the array can be programmed to flash synchronously (in unison), the preferred pattern is a timed sequence that follows the curve. System features include programmable pace and duration of flashing, triggering speed and flash pattern. Check out the Sequential CWGS video!
