Abstract: An auxiliary external rearview mirror apparatus which is adapted to be mounted to existing external vehicle mirrors of substantially any size or shape to provide the driver or other occupant of the vehicle with an enhanced view of the roadway. The auxiliary external mirror apparatus comprises an auxiliary mirror member, first and second support arms for mounting the auxiliary mirror member to an existing external mirror member of a vehicle, and securing means adapted to extend around the back side of the existing mirror member from the first support arm to the second support arm to secure the auxiliary mirror apparatus to the existing mirror member without covering the existing mirror to any significant extent. The auxiliary mirror apparatus is of streamlined shape and extends from the existing mirror member along substantially the same line that the existing mirror member extends from the vehicle.
