Two teenage girls say that the LED bracelets they received at the Baton Rouge Taylor Swift concert may have saved their lives.

Elizabeth Dazzio was driving her sister Caroline and a friend home from the show last week, when she fell asleep at the wheel and crashed the car. The girls were trapped in the car and said that they could smell gas and smoke.

Two of the three cell phones in the car were dead, so the girls used the LED bracelets to flag down drivers that were passing by. A woman saw the lights, pulled over and helped the girls out of the car until emergency personnel arrived.

The bracelets were given to every concert attendee, and were synced up as part of the light show.
