BlinkerSign Flashing LED Chevron traffic warning signs increase safety on dangerous curves. The solar-powered units are cost-effective because they require no trenching to install and no power supply. The LEDs in the signs adjust to ambient light levels automatically, and can be seen from up to two miles at night. The solar traffic signs, which are FHWA/MUTCD-compliant, can be programmed to flash in sequence or in unison. The system communicates wirelessly, so the signs can be activated by vehicles approaching the curve too fast.
