A line of heated windshield wipers–which connect directly into the vehicle’s ignition system to start de-icing immediately and stop ice and snow from building up while driving–is offered by Northland Engineered Products. Operated by an on/off switch, they feature a built-in etched foil heating element along with Nordel elastomer wiper blades. Ideally suited for motorhomes, trucks and buses, the wipers are supplied with adapters to fit most wiper arms. They are available in 13- to 20-inch sizes and have a non-glare black finish.
