Various embodiments of a warning indicator (100) for use with wiper blades are provided. In one embodiment, the warning indicator has a housing (110, 110'), a counting unit (120) disposed in the housing, an indicating unit (150) exposed on the housing and an electrical source (160). The housing is coupled to an oscillating wiper blade (210, 220) 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.
