Namely the ON/OFF state of each color of the signal 10 is detected by a synchronization detector 21 without changing an electric circuit in the signal 10. Plural information data are successively switched and displayed on the panel 20 synchronously with the switching of the lighting color of the signal 10 based upon the detection output of the detector 21 and the emitting color of the background is switched so as to be turned to the same color as the signal 10. Consequently various information can be displayed on the panel 20 and the signal color can be confirmed by both of the signal lamp and the display color of the panel 20.
