ABSTRACT:
A plurality of light-emitting diode elements are disposed in a generally cylindrical outer frame of an indicator main body. Recesses are formed on the outer surface of the outer frame so as to be arranged in its circumferential and longitudinal directions. Several ribs are formed on the inner surface of a hood so as to be arranged in its circumferential direction. The ribs of the hood are fitted in selected ones of the recesses of the outer frame to form an indicator. A display panel is constituted by two-dimensionally arranging a large number of the above indicators on a base.
