Orion's road flares utilize the same formula that professionals like police officers use. They're completely safe, and each flare provides 15 minutes of high visibility, even in adverse weather conditions, to keep you and your family safe in the event of a breakdown on the side of the road. They come in a resealable bag that keeps moisture away from the flares, so you can rest easy knowing that these flares will be ready to go for you in the event that you need them, even if they've been sitting in your trunk for months on end. | Orion 3-Pack 15-Minute Emergency Road Flare
