The song was released on May 15, 2017, by JYP Entertainment and distributed by KT Music, as the lead single from their fourth extended play of the same name. The Japanese version of "Signal", along with its accompanying short version of the music video, was released on June 14, 2017, as a promotional single for their first Japanese compilation album, #Twice.
On May 1, 2017, JYP Entertainment announced Twice's comeback with their fourth EP Signal and its title track of the same name. The first music video teaser of "Signal" was uploaded online on May 13. It was released on the 15th as a digital download on various music sites.[2][3][4] In June 2017, Twice released a compilation album titled #Twice which consists of ten songs including both Korean and Japanese-language versions of "Signal".[5][6][7] The Japanese lyrics were written by Yu Shimoji and Samuelle Soung.[8] "Signal (Japanese ver.)", along with its accompanying short version of the music video, was pre-released on June 14 as a promotional single of the album.
"Signal" was written by Park Jin-young and co-composed by Park and Kairos. This marked Twice's first collaboration with their agency's founder. The electropop song features a programmed Roland TR-808-style kick and hi-hat with incorporating hip hop elements.[1][10][11] Lyrically, it expresses a girl's frustration who keeps sending "signs and signal" to hint her feelings for a guy but is unnoticed.[12]
