Three Louisiana girls say that bracelets from Taylor Swift's show saved them after a car crash.

Elizabeth Dazzio was driving her sister, Caroline, and a friend home from Swift’s concert last week when Dazzio fell asleep behind the wheel and crashed her car. The impact knocked her unconscious and left her passengers trapped inside.

Two of the girls’ phones were dead, and the third was missing. That’s when the girls made the swift decision to use light-up bracelets from the concert as impromptu emergency flares.

A driver saw the lights, pulled over and called for help.

Swift tweeted a link to the WBRZ 2 article on the crash and wrote that she’s “so happy” that the three fans are OK.
