A mirror reflector is disposed at at least a portion of a surface of a rear substrate of the reflective element. The mirror reflector includes a stack of thin films having at least a first metal thin film and a second metal thin film. The first metal thin film is formed of a metal material that has a specific resistivity of less than about 1×10−3 ohm·cm and the second metal thin film is formed of a metal material that has a specific resistivity of less than about 1×10−3 ohm·cm. No part of the rear substrate extends beyond any part of a front substrate of the reflective element. An indicator is disposed rearward of the reflective element and, when actuated, illuminates through the reflective element.
