A solar battery indicator apparatus utilizing a capacitor for accumulating electrical power generated by the solar battery and light emitting diodes for emitting light on the basis of the electrical power supplied from the capacitor. An indicator body makes a prescribed indication on its front surface through the use of optical fibers. Several bundles of optical fibers are utilized with each bundle being associated with a plurality of optical fibers having one of their ends disposed to face an associated one of the light emitting diodes and the other end of each of the bundles of fibers being associated with a particular indicator. The configuration of optical fiber bundles utilize a control portion for controlling light emitting states of respective individual light emitting diodes. In another aspect a bundle of optical fibers have their connection to a light emitting diode such that the light emitting diode and the connection is positioned substantially in the center portion of a sign indicator controlled by the light emitting diode so that the curvature of the individual optical fibers is within a range for optimal light transmission.
