Infrared Sensor Detection

Our innovative Overheight Warning System uses infrared beams mounted on either side of the road to precisely measure the height of vehicles as they travel past the sensor. When the sensors detect an overheight vehicle, the attention-grabbing warning lights are triggered to alert drivers to the upcoming hazard.

BlinkerBeacon™ or BlinkerSign® Warning Alerts

We offer a variety of MUTCD-compliant BlinkerBeacon™ and BlinkerSign® LED warning alerts and mounting options that can be tailored to meet each installations needs. View our Application Sheet to see the different options.
