Abstract
Described is a wiper blade for a windshield of a vehicle. The wiper blade having a frame structure, a squeegee, and a conductive strip. The squeegee is coupled to the frame structure and includes a wiping lip. The conductive strip is formed on a side wall of the wiping lip. The conductive strip extends along a length of the wiping lip. The wiper blade can also include an indicator, such as one or more light emitting diodes, to indicate a physical condition of the wiping lip.
