The respective electrodes may be connected to each other.

Further, the arrangement of the bins between the indicator lights 38 and the bracket 39 is determined in advance so that power is supplied to each of the indicator lights 38.

"Effects of the Invention" As explained above, according to the indicator light according to the present invention,
A transparent or milky white globe contains multiple light-emitting elements that emit light of different colors to emit light in the desired color, so it is much easier to use than conventional indicator lights that have a globe for each color. Even if the number of displayed colors is increased, the overall shape will hardly increase, and there is also an advantage that there is no need to rearrange the respective gloves as in the conventional case.

Further, by using a flexible substrate as the light emitting element mounting member, the degree of freedom regarding the shape of the glove can be increased to some extent. Furthermore, by using a structure in which a plurality of boards on which light emitting elements are attached are laminated as the light emitting element mounting member, it is possible to have more freedom in the shape of the globe than in the case of the above-mentioned flexible panel board. .
