The judge of 'The X Factor' has also shared some photos taken on the video filming set after she reached 20 million followers on Twitter.
The short teaser also gives glimpses at Lovato joining her friends for a rowdy party in a warehouse and putting on glow-in-the-dark make-up. According to Lovato, the full music video will arrive on November 21.
Before dropping the sneak-peek video, Lovato tweeted some photos taken on the video filming set. She did it to celebrate her 20 million followers on the social networking site. "Since I passed the 20 million mark... I'll release some early sneak peek pics from my new video #NEONLIGHTS," she captioned a photo of her lying on the floor and slightly arching her back.
In another photo, Lovato wears neon-colored eye shadow, lipstick and nail polish when staring at herself in a mirrored reflection.
"Neon Lights" is featured in Lovato's self-titled album, "Demi", which was released earlier this year. To support her latest studio set, Lovato is set to go on "Neon Lights" tour that kicks off in February next year.
