Mercedes Benz Wiper Blade 4478205400

A windshield wiper or windscreen wiper is a device used to remove rain, snow, ice, washer fluid, water, and/or debris from a vehicle's front window so the vehicle's operator can better see what's ahead of them. A wiper generally consists of a metal arm; one end pivots, the other end has a long rubber blade attached to it.

The arm is powered by a motor, often an electric motor, although pneumatic power is also used for some vehicles. The blade is swung back and forth over the glass, pushing water, other precipitation, or any other impediments to visibility, from its surface.
