A rearview mirror assembly for a vehicle includes an electrochromic reflective element having a specularly reflective perimeter layer established at least partially around a perimeter border region of a second surface of a front substrate. The perimeter layer is, at least in part, visible through the front substrate to a viewer when viewing the first surface of the front substrate of the reflective element. The perimeter layer conceals at least a portion of the seal from direct view by the driver of the vehicle. At least one of (a) at least one light source is disposed behind the perimeter layer and emits light that is visible to a viewer viewing the first surface of the front substrate of the reflective element at the perimeter layer, and (b) a light sensor is disposed behind the perimeter layer and senses light that passes through the front substrate at the perimeter layer.
