Always be prepared for an emergency with your Emergency Magnetic Light. Keep the Light in a place, where you'll always know it is there. The two magnets on the back of the light holder allow you to stick the light on your fridge, water cooler or any magnetic surface. When the lights go out, you'll always know where your emergency light is. The top of the light holder even has a glow in the dark panel to help you find it in the dark. Simply remove the light from the body of the holder and the light turns on. Return the light back into the holder and the light automatically turns off. Not only is this a convenient and perfect emergency tool, but it's also a great key chain holder. You'll never have trouble with lost keys as long as you place them on your Emergency Magnetic Light holder. This set includes one black and one white.
