Advance Curve Warning Alerts

A flashing LED Curve Warning BlinkerSign® warns drivers they are approaching a curve. Choose the MUTCD curve legend that best represents the curve where it will be installed. The LED sign can be programmed to flash 24/7 or at preferred times, or it can be activated by approaching vehicles with a radar detector mounted on (or in advance of) the sign.


BlinkLink®, powered by TAPCO, is an easy-to-use, cloud-based application cities leverage to manage, schedule, control and monitor system-wide time clocks and intelligent warning systems.
