Abstract
Abstract A vanity mirror assembly, which can be lighted, and which can be built into a sun visor for an automobile or other motor vehicle. Electrical components including a heat-dissipative component are screen-printed on a polymeric film substrate mounted adhesively to the back face of a glass mirror, which serves as a heat sink for such components. Shards of the mirror tend to be adhesively retained by the substrate if the mirror happens to shatter.
