Between the two shocking probes, there is an LED Flashlight. Unlike other flashlights which just use a small LED on the surface or a group of LED bulbs, a reflecting cup and LED bub is used in our light. This combination creates a super bright flashlight for use in the dark. There are two red flashing warning lights on both sides of the stun gun. When these lights are turned on, it will flash brightly and rapidly. Use to attract attention, especially at night. Can be useful during an attack or other emergency situations such as car trouble. Sirens are readily recognized as an emergency call for help. Use the 110dB alarm to draw attention to yourself in the event you are attacked or in a situation where you feel your life is threatened. Never needs batteries because it's rechargeable. Battery charger included. These batteries have been tested and proven to deliver maximum power for 800 to 1000 recharges.
