Those are smoke canisters that are ignited and continue to burn until they are depleted. i.e.; no way to shut them off. I would submit that a quick shut-down is a design requirement, so that you don't get your brains blown out all over the road or sent to Guantanamo.
Darin's description of the hypodermic tube with current passing through it sounds like the best idea to me. Anyone know where you can find such small tubing in small quantities?
