Abstract: The automobile proximity sensor and warning display is mounted on an outside rear view mirror of a vehicle. A flat base plate, adhered to the outside mirror, coacts with a removable body on a front side of the base. The battery powered system includes a proximity detector, responsive to approaching vehicles, generating an alarm signal sent to a lighted display. The body may have a removable mirror. The body may be coupled to the base by complementary coupling sub-systems or an insertable body portion coacting with a shelf on the base wherein a depressible tab is sized to fit within a shelf orifice. As a power saver, an accelerometer detects motion and a timeout circuit turns OFF system power when no motion is detected for a predetermined period of time.
