A great little lightbar
I supervise a security crew at a small industrial site. This light is great for our purposes. The design allows maximum reflection to be visible from a good distance. Even in daylight, the light is noticeable. Other units we've tried are worthless on sunny days. It doesn't show up as well from a great distance as a wider light bar, but again, on a small site it's great. We're now waiting to see how it lasts in cold, snowy weather. We have found that the rubber "boots" come off of the magnet mounts fairly easily after rainfall. The boot becomes a "suction cup" when wet, and the magnet mound slides out of it. However, if one is aware of this and is careful, it still provides good protection against scratching the roof.
