Our Popup Cones are easy to store and can fit easily under most car seats. These are great if you get stranded with a car out of gas or in a minor accident with a tree or light pole. These Popup Cones are durable and waterproof. The flashing lights will burn for 36 hours straight, which means that in your time of need, these lights will guide rescue directly to you. The weighty base means these will stay put much better than signal flares that may roll away in high wind. They are available in two sizes and if you buy four, you get a carrying case that will hold all four for free. Be prepared for any emergency.
