PROBLEM TO BE SOLVED: To provide turn indicator lamps for clearly distinguishing between "opening" and "closing" of a door so as to be visually understandable with anyone. SOLUTION: Color changeable type turn indicator lamps distinguish "the opening" and "closing" of the door in lights of different colors, or through the difference between lighting and flashing, or by first and second type flashings of different types. It is also possible to distinguish whether the purpose of switching on the turn indicator lamp is to turn the next crossroads or change lane by including either one or both of the following functions that after travelling legal several meters after which it is admitted to start turning since when the turn indicator lamp is flashed, or after an elapse of legal seconds after which it is admitted to start turning, flashing of a color different from the flashing color during the initial legal meters, or flashings at different time intervals between the flashings are carried out.
