Instead of flares I would suggest getting a set of 3 warning triangles. Flares can be very dangerous. I once had the "pleasure" of watching a flare get clipped by a passing car and flipped up through the open window of a police car. Didn't take long before flames were shooting out of the car. But you are on the right track with mentioning some kind of warning device. For me: Warning Triangles Duct tape Multi bit screw driver and any extra specialty screw drivers that might be needed. 2 quality adjustable wrenches. Spare fuses and bulbs. jack and lug wrench can of silicone lubricant. super glue. screen repair kit (when I had the pup) canvas repair kit and seam sealer. assortment of sewing needles and a spool of black thread. Utility knife scissors.
