A thermally regulated electrical deicing apparatus with a flexible cover portion is mounted to an exterior surface of a vehicular windshield; the flexible cover portion includes an electrical deicing element with either a resistance element heat tape or a serpentine woven heating element directed therethrough in electrical communication with an alternating current power supply. A thermistor effects selective heating in the heating element. The electrical deicing element further includes a male alternating current electrical plug conducting current to the heating element through an electrical power supply line, wherein the thermistor is interposed between the male alternating current plug and the heating element, and controls the current conducted to the heating element; and a female alternating current electrical plug attached to the power supply line, which provides a connection means for a second thermally regulated electrical deicing apparatus.
