This is the 4 1/2'-high beacon that affixes to the roof of a car to provide superior visibility in an emergency. Unlike roadside flares, window-mounted triangles or a car's flashers, which are all low to the ground, this extra tall beacon is elevated so it can be seen from a distance, making it easier for first responders to locate a disabled vehicle and giving oncoming traffic more time to slow down. The beacon contains 16 ultra-bright red and white LEDs that flash a 360-degree warning signal that lasts for 10 hours. A vertical setting also beams a light upward to attract attention when a car is stranded in a ditch or low area. The collapsible 4' pole snaps together in seconds and is topped with an orange pennant, and the base is magnetized so it adheres to a car roof. The kit stores neatly in a trunk and contains a flashlight and orange safety vest. Comes with three AAA lithium-ion batteries. 18" H x 16" W x 4 1/2" D (3 lbs.)
