Variable intermittent windshield wipers are a type of windshield wiper that automatically adjusts the speed and frequency of the wipers based on the amount of rain or snow falling. This type of wiper is more efficient and effective than traditional wipers, as it can adjust to changing conditions without the driver having to manually change the settings.
Variable intermittent windshield wipers typically have a sensor that detects the amount of rain or snow falling. The sensor then sends a signal to the wiper motor, which adjusts the speed and frequency of the wipers accordingly. Some variable intermittent windshield wipers also have a setting that allows the driver to manually adjust the sensitivity of the sensor.
