A cold-light indicating and warning meter for car mainly includes a plurality of concentric cold-light rings simultaneously provided on a surface panel of the meter. With a control unit of the meter, readings representing engine speed, car speed, engine temperature, fuel level, etc. are separately shown on the same meter via light and shade of the cold-light rings, so that a driver may have an idea about the conditions of the whole car by observing only one meter.
