Zusammenfassung: | A light indicator comprises a light source, a storage battery, a printed circuit board, and a first light-guiding bar. The light source is electrically connected to an external power source and the storage battery is electrically connected to the light source and the external power source respectively. The printed circuit board is provided with a switch circuit and is electrically connected with the external power source and the storage battery. Via the switch circuit, when the external power source stops providing electricity to light source, the electrical source can be switched from the original external power source to the storage battery in order to provide electricity continuously for illumination of the light source. The first light-guiding bar is provided in front of the light source and the light emitted from the light source will travel through the first light guiding bar to produce light indicating effect. |
