Mirror assembly with heater element

A mirror reflective element system has a front substrate having a first surface and a second surface, the second surface having a transparent second surface electrically conductive coating disposed thereon, and a rear substrate that has a third surface and a fourth surface, the third surface having a third surface electrically conductive coating disposed thereon. An attaching surface of a heating element is attached at the fourth surface. The heating element has an electrically conductive heating element established thereat and includes first and second electrically conductive traces. The electrically conductive heating element and the first and second electrically conductive traces are electrically isolated from one another. The first electrically conductive trace provides, at least in part, an electrically conductive connection to the transparent second surface electrically conductive coating, and the second electrically conductive trace provides, at least in part, an electrically conductive connection to the third surface electrically conductive coating.
