Pro Led 2620A Battery Operated, Magnet Mount, Amber LED Light Beacon with Rotating Flash Pattern

I've been using his light on my pickup truck when I plow snow for the last three years. It takes four AA batteries and my first set lasted longer than two seasons before I decided to replace them. The on/off switch is a button on the underside of the magnetic base. The internals of the light are protected from rain or snow under normal circumstances. There are no moving parts and the LED lights are synchronized to appear that the beacon is in constant movement, but it is not. The light stays where it is placed on any magnetic surface and will not blow off when the vehicle is driven on the highway at legal speeds. It can be knocked off if you drive under a low hanging wire or limb, but that is completely understandable. I keep it inside my truck, turn it on, and mount it after I clean the snow off my truck roof after every new storm. When the job is finished, I remove it, turn it off, and put it back in the cab until the next time I need to use it. If you plow snow, this is the light for you, especially if you don't like maneuvering light cords and cigarette lighter plugs within your cab.
