You just stole a headlamp off my bike. You now have a $40, presumably broken, headlamp.. as you could not have possibly had the time to steal it with a screwdriver in the 45 seconds I looked away. The bike you stole it from cost me $5000. It was unlocked. Free for the asking. You probably could have gotten away with it. And you went for the headlamp. Instead of the $5000 bike. Good job.
