An exterior rearview mirror for vehicles, in particular motor vehicles. The exterior rearview mirror has a mirror housing with a mirror glass, which is mounted on a mirror glass support and is encompassed by a frame. The exterior rearview mirror is provided with signal lamps, area lights, and indicator lights that are situated in the mirror housing or in the mirror base. In order to permit a simple, inexpensive installation of a lamp into the exterior rearview mirror so that it does not take up much space, at least one lamp of a built-in light is accommodated in the frame. The lamp, which is fastened to the frame in a non-detachable way, can be accommodated in the frame in a simple, space-saving way and held there securely. The exterior rearview mirror is particularly suited for motor vehicles.
