If you feel as though you must bring a cigarette lighter on a plane, look around for one of these 80s-vintage wristwatch lighters. If a TSA agent stops you at security, tell him/her the flame is to let you see the display in the dark.
"I picked up this unique watch/lighter at a garage sale as a teen in the late 80s for $2 (price tag remains on box). I've never seen another one like it. Always thought it was an interesting combination. I have a small collection of vintage novelty watches, and this is my favorite."
