Collapsible Warning Triangles are a perfect addition for any vehicle safety kit and can be used day or night to alert other drivers of disabled vehicles and roadside emergencies. The kit includes three large red reflector warning triangles that are easy to set up and fold down. The triangles have a weighted base so that they will not blow away or knock down from passing vehicles. Each triangle measures 17 inches wide by 17 inches high. The triangles store in a convenient plastic case.
