A wiper is the arm-and-blade unit that sweeps rain and dirt off the windshield.

A motor drives the arms back and forth so the rubber blades wipe the glass clear; worn blades streak and reduce vision and are replaced regularly.

Wipers are fitted on the windshield and sometimes headlamps. The correct arm and blade match the vehicle and screen size, and good wipers support safe driving.
