Although not a “survival lighter” per se, I would like to see someone make a friction-fit, glow-in-the-dark cap that would slide over the end of a BIC lighter—both regular and the mini BICs. Such would not add much to the overall size of the lighter and would keep water, dirt, and pocket lint out the business end of the lighter. It would also protect the gas-release thumb lever from being accidentally depressed. A lanyard hole could be molded into this cap. The friction fit should be loose enough to conveniently remove the cap but tight enough that the lighter does not fall out of the cap when carrying the lighter by a lanyard or on a key chain. When using the lighter, the cap could be pressed onto the other end of the lighter so it does not get lost.
