A motor vehicle light assembly includes a housing; a light source disposed in the housing, and a light-transmissive lens operably attached to the housing. A heater member is disposed between the housing and the light-transmissive lens. The heater member is configured to radiate heat emitted from the light source, with the heater member being routed to direct the radiated heat onto the light-transmissive lens to regulate the temperature of the light-transmissive lens to inhibit fogging, frosting and icing of the light-transmissive lens.
