1. A heated illumination assembly, comprising:
a lens cover defining a first region and a second region;
a first heater member having a first electrical resistance, disposed in the first region to heat the first region;
a second heater member having a second electrical resistance different from the first electrical resistance disposed in the second region to heat the second region;
the first heater member and the second heater member configured to be selectively electrically coupled to at least one power source to receive at least one of a first current and a second current, respectively therefrom;
a controller module arranged to receive at least one input signal, and configured to selectively electrically couple at least one of the first heater member and the second heater member to the at least one power source, based on the at least one input signal;
a first electrical control device communicatively coupled to the controller module, the first electrical control device electrically coupled to the at least one power source to receive electrical power therefrom, and selectively electrically coupleable to the first heater member to provide the first current thereto;
a second electrical control device communicatively coupled to the controller module, the second electrical control device electrically coupled to the at least one power source to receive electrical power therefrom, and selectively electrically coupleable to the second heater member to provide the second current thereto; and
wherein the controller module is further configured to control a respective operation of the first electrical control device and the second electrical control device.
