TRICO Signal™ is engineered with a patent pending, Predictive Performance Indicator (PPI™), a visual indicator of when it is time to monitor or replace your wipers. The Predictive Performance Indicator has an exclusive colored core that is integrated into the silicone ceramic wiping element. To check the status of your wipers, regularly lift your wipers off the windshield to check the rubber. When you start to see the red core visible, it may be time to replace. It's that simple!
