TAPCO's LED-enhanced BlinkerStop sign technology provides high visibility both day and night. Each LED produces more than 600 candelas to maximize conspicuity. The LEDs provide greater distance visbility than conventional signage or beacons.BlinkerStop is particularly effective in bringing rolling stops to a complete stop. Numerous tests have shown it to be a great aid in accident reduction or elimination. Safety can be enhanced in the same amount of time it takes to install a standard traffic sign because BlinkerStop is 100 percent solar powered and completely self contained.
