Abstract
Various embodiments of a warning indicator for use with wiper blades are provided. In one embodiment, the warning indicator has a housing, a counting unit disposed in the housing, an indicating unit exposed on the housing and an electrical source. The housing is coupled to an oscillating wiper blade of a windshield wiper device. The counting unit is configured to detect oscillating movements of the wiper blade one at a time. The counting unit is configured such that an oscillating number of the wiper blade is accumulatively increased. The indicating unit indicates a warning under control of the counting unit when the oscillating number comes to a predetermined value. The electrical source supplies an electrical power to the counting unit and the indicating unit.
