A Tralight has the appearance of a traffic light with faces on each of its three colored lights. A Tralight has one set of arms for each light (six arms in total) and two legs.
A light will light up according to its emotions (Example: If a Tralight is joyful, the green light will light up). Tralights usually only control the arms nearest to the light which is shining. They can also control how much light is given off. It can use a bright light for seeing at night or in the dark.
- Its name is a portmanteau of "traffic" and "light" due to its appearance.
