The reflective element has a front surface and a rear surface and a first reflector portion and a second reflector portion, with the first reflector portion having a first reflective coating disposed thereat. The auxiliary wide angle element is disposed at a rear surface of the glass mirror substrate of the reflective element and at the second reflector portion. The auxiliary wide angle element has a glass element having a curved rear surface with a second reflective coating disposed at the curved rear surface. An optical coupling element may be disposed between a front surface of the auxiliary wide angle element and the rear surface of the reflective element, the optical coupling element may be a substantially optically clear and flexible elastomer.
