Abstract

A vanity (mirror assembly includes a flexible circuit which extends between a movable cover and a vanity mirror frame and provides circuit capabilities for mounting lamps on either the cover or vanity mirror frame. Other circuit elements such as control switches, dimming controls, and the like can be mounted on the opposite side of the vanity mirror package so that a relatively thin visor with spaced-apart circuit elements can be provided. In the preferred embodiment of the invention, the circuit comprises a flexible insulative substrate which comprise first and second circuit panels integrally interconnected by a bridge. Conductive elements are screen printed on the first and second circuit panels and on the bridge which extends across the pivot connection of the cover to the mirror frame while coupling the first and second circuit panels.
