Concert wristbands are cool enough. They’re bright and you can keep them after a gig or festival as a keepsake from the great times had, but besides their sentimental value and their obvious logistical function inside of a venue, are wristbands all that useful?

Well, according to three girls who recently ran into a spot of trouble following a Taylor Swift show, concert wristbands are potential lifesavers. The story goes like this (via Billboard) Elizabeth Dazzio was driving her sister and a friend home after a Swift concert in Louisiana.

However, disaster struck when she fell asleep behind the wheel and the car crashed. According to the local WBRZ station, Dazzio was knocked unconscious and the two other girls were trapped inside of the mangled wreckage of the car.

“You could smell the gas and smoke,” Caroline Dazzio told WBRZ. “I was just thinking we need to get out of this car.” Unfortunately, their phones were dead and they had no way of signalling passing cars to help them.

Luckily, the girls had the bright idea of using the light-up wristbands given to them at the Swift show, which had been programmed and synced to the beat of the music, as makeshift emergency flares to get the attention of people driving by. It worked.

Eventually, a passing car did stop, with the woman inside telling the girls that she saw the lights and knew someone was in trouble. “She could tell that there was someone in the car,” Caroline told WBRZ. The woman and a man with her helped pull the girls out and called for first responders.

Thankfully, Dazzio is expected to be released from hospital soon and the story even caught the attention of one Ms Taylor Swift, who shared the story of the girls on Twitter and was glad to hear that they’re doing well.

On the one hand, this proves that it’s a good idea to hold onto your concert and festival wristbands, especially if they happen to be wired with flashing lights. On the other hand, it’s just another day of good PR for Taylor Swift.
