This small device provides the benefits of a much larger display all in the palm of your hand. It's light weight and well balanced and best of all goes very easy on batteries. It offers 3 settings: half on, full on and flash. At one end is a flashlight.
The most remarkable aspect of this light is that when you set it to full on mode and wave it in a large arc, it appears to drivers at any distance up to half a mile away as an 8 foot traffic warning signal. It's really quite amazing and I was so impressed, I ended up buying myself a second one. Be sure to get yourself the red or yellow cone tip as well as the magnetic holder that you can attach to your squad car.
