Windshield wipers, also known as windshield wiper blades or squirgees, are an essential part of a car's safety system. They are used to clear rain, snow, and other debris from the windshield, allowing the driver to have a clear view of the road. Squeegees are the most common type of windshield wiper, consisting of a rubber blade attached to a metal arm that is connected to the car's windshield wiper motor. The rubber blade is designed to wipe away water and debris from the windshield, while the metal arm moves the blade back and forth across the windshield.
