Traffic Light.

Traffic Light. (トラフィックライト。) is a sub-group of MeseMoa. consisting of Kimagure Prince, Shirofuku and Aoi. The name Traffic Light. is derived from the fact that Japanese traffic lights are said to be red, yellow, and blue. The group was formed to help promote MeseMoa. through traditional methods such as promotion in music shops, advertising, and the radio.

Traffic Light. released their debut single in 2016 under the Victor Entertainment label, reaching #9 on the Oricon Weekly Chart. They've also had tie-ups with TV shows and other brands, and their song Perfect World was used as the 4th ending theme to the Digimon: AppliMonsters anime. The members are often grouped together for MeseMoa.'s activities, but they have not been active as a sub-group since 2018.
