Condensed breath vapor is removed from visors on helmets adapted to be used by drivers of open air outdoor vehicles, such as snowmobiles, motorcycles, and all terrain vehicles, by applying electric current to a resistance heater coil on the visor. The heating coil is electrically connected to a connector mounted on the visor. The connector is electrically connected by a helically coiled cable to an assembly mounted on the vehicle dashboard. The assembly includes a female jack for receiving a male jack at the end of the coiled helical cable. The assembly also includes a switch for connecting the jack to a power supply of the vehicle, so that electric energy from the power supply can be coupled selectively to the female jack at two power levels.
