This invention recognizes the hazards of beryllium and beryllium oxide in automotive applications and offers alternative material solutions. In particular, commercial electrochromic mirrors use beryllium comprising alloys for busbars and may also use beryllium oxide for the electronics used to power and control these mirrors. Further, this can be combined by reducing other known hazards such as mercury, cadmium, lead and antimony compounds.
