I have expressed my wishes for a short duration road flare for fire starting purposes and of course Orion makes them. This is a 5 minute version of a red road flare, 5-1/4" long and it weighs 3.4oz.
I hike solo in the deep, dark, wet woods and I count fire making as a critical skill and part of my safety cushion. Road flares will get the wettest, rotten nasty wood burning in a hurry. Of course, you get a handy dandy signal device in the same package. I plan to carry one along with my usual bic/matches/firesteel/tinder collection. I think canning them in a Seal-A-Meal bag is a good way to go.
These things are expensive and very hard to find. If hiking with a group, I think I would lean to a standard 15 minute road flare, but it was hard to resist a small light package like this. The twin pack is Orion part number 750 and UPC 077403107506.
