An electrochromic vehicle mirror which can be alternatively darkened or lightened to decrease or increase reflectivity comprising in the order indicated:
- a glass substrate;
- a conductive coating thereon;
- one of an anodic electrochromic layer of nickel hydroxide and a cathodic electrochromic layer of tungsten oxide;
- a solid electrolyte layer;
- the other of said cathodic electrochromic layer and said anodic electrochromic layer;
- and
- a layer of a reflective/conductive material;
- where said anodic nickel hydroxide electrochromic layer has a thickness of from about 300 to about 600 angstroms, said solid electrolyte layer has a thickness of from about 1000 to about 1500 angstroms and said cathodic tungsten oxide electrochromic layer has a thickness of from about 600 to about 1200 angstroms.
