Ball lights. - Brite Strike Technologies Tactical Balls White LED Rolling Devices

I find that these lights are lacking for their intended use. If these had activation on landing with a high intensity strobe light setting. These would be a much better device. Add a high pitch high db alarm that activates with the strobe light. Then you would truly have an effective distraction device. As is, I found them to be great as an emergency lighting system for any occasion. I recently used them during a power outage. Bounced the light off the walls, and one effectively lit up the room. I also used them as yard lights for night parties in my backyard.
