The Everblades Heated Windshield Wiper Kit uses calibrated-heating elements on the silicone blade and metal frame that reach 230 degrees F to ensure better visibility in severe winter cold weather. These blades are suited for commercial applications such as snow plows, buses, and heavy-duty trucks, and use commercial-grade wires that  are engineered to resist road vibration and remain flexible in extreme cold. Kit includes two blades, heat control switch, wiring harness, and fuse. Installation can be completed in under 30 minutes.
