For wiper systems, rubber-wiping elements are one of the key components ensuring excellent wipe quality and, therefore, satisfying driver visibility, security and comfort. In order to track the rubber element wear precisely and to know when the blades have to be changed, a wear indicator for the rubber element has been developed. The indicator is made of a black plastic material with an adhesive, pressure sensitive, backing located on the main bow. With time and external stresses, the sticker turns a green color at mid life, and yellow at the end of life. Yellow color indicates to the driver, the end of the effective life of the wiper blade.
