Firework ignitor..guitar?

Im taking a project guitar and took the guts out of the neck pickup, im trying to make it "loadable" for smoke bombs, and im trying to find a way to electricly ignite them with a on. I dont want to have to use a match or lighter. I need something that is realitvely small, runs off batteries, and with push of on/flip of swtich can ignite the Green(string) fuse of the firework smoke bombs. Is there anything out there. Im sure there is but idk the name or where to start.
