Heated windshields are designed to improve visibility by quickly melting ice and snow. They use a thin layer of conductive material, often made of metal, embedded within the glass. When activated, an electrical current heats the windshield, allowing drivers to see clearly in cold weather conditions. These windshields are commonly found in many modern vehicles, especially in regions with harsh winters. They can be activated with a simple switch, providing a convenient solution for defrosting. Heated windshields enhance safety by reducing the time needed to clear obstructions, making driving in winter weather more manageable.
