Taylor Swift may have just saved the lives of three teens.

And she did it using the power of the programmable LED bracelets fans get when they attend Taylor's 1989 World Tour concerts.

Elizabeth Dazzio, her sister Caroline, and a friend were driving home from the second night of Taylor's U.S. tour in Baton Rouge, Louisiana, last Friday when Elizabeth fell asleep behind the wheel and crashed the car.

"You could smell the gas and smoke," Caroline told Baton Rouge TV station WBRZ. "I was just thinking we need to get out of this car."

With Elizabeth unconscious, the two girls trapped inside the car tried to use their phones, but they were dead. They then turned to Taylor's bracelets, which were still illuminated and programmed to light up to the beat of T. Swift's music.

The girls started tapping the bracelets on the car windows as they flashed, and eventually a woman pulled over to help and call 911, according to Avery Talbot, a friend of the teens who wrote about the incident on Taylor Swift's Website.

Taylor tweeted out the news on Thursday, calling it "unreal," but is "so happy" that her fans are OK. Elizabeth is expected to be released from the hospital soon.
