A heated illumination assembly includes a light transmissive lens cover defining a first region and a second region. A first heater member having a first electrical resistance is disposed in the first region, and a second heater member having a second electrical resistance different from the first resistance is disposed in the second region. A controller module is configured to selectively electrically couple at least one of the first heater member and the second heater member to at least one power source, based on an input signal.
