A heater system for an LED light assembly having a lens includes a flexible composite positioned around an outer surface of the lens. The flexible composite includes a polymer base layer, a plurality of conductive buses provided on the base layer, and a resistive layer electrically connecting the plurality of buses to form a circuit. The resistive layer includes conductor particles dispersed in a polymer matrix. The resistive layer has a crystalline first condition prior to applying electricity to one of the buses and an amorphous second condition in response to applying electricity to one of the buses.
