Abstract
Abstract A mirror assembly for a vehicle. A small, flat mirror is mounted through use of a wedge-shaped adhesive block to the inside portion of a conventional side view mirror. The block positions the small mirror at an angle of about 15° to 20° with respect to the plane of the side view mirror to thereby eliminate the "blind spot" to the side and the rear of the vehicle.
