Heated wiper blades are designed to improve visibility during winter weather by preventing ice and snow buildup on the wiper surface. These blades contain a heating element that warms the rubber, allowing it to clear away frost and snow more effectively. This feature is especially useful in regions that experience harsh winter conditions. Typically, heated wiper blades are activated when the vehicle's defrost system is turned on. They can be installed on most vehicles and are often used in conjunction with other winter driving aids, such as defrosters and heated windshields, to enhance overall safety and driving comfort.
