This Personal Alarm combines a loud 120 dB alert alarm with a flashing safety light. It emits a 120 dB siren and flashes a bright red LED strobe light to ward off an attack and signal for help. The light and siren alarm are both activated by removing the pull-cord pin. Flashing safety strobe can also be separately turned on and used as a safety light while walking, jogging or biking. Can be used with Door Clip Accessory #20-8104.
