Description of the Related Art Conventionally, as disclosed in, for example, Japanese Utility Model Laid-Open No. 58-4029, a probe provided on a plug of a housing for accommodating a battery liquid and between the probe and the negative electrode. A liquid level detection device for a storage battery has been proposed, which includes a resistor and a light emitting diode that are connected in series with each other. In this conventional liquid level detection device, when the liquid level of the battery liquid in the housing is at a predetermined height position, the probe penetrates into the battery liquid, that is, the probe comes into contact with the battery liquid. A circuit is closed between the negative electrode and the negative electrode, and accordingly, the light emitting diode is lit by energization. On the other hand, when the liquid level of the battery liquid is lower than the above-mentioned height position, the probe is in a state of being separated from the liquid level of the battery liquid, so that the circuit between the probe and the negative electrode is cut off and the light emitting diode is Turn off the light. Since the light emitting diode is turned on or off according to the liquid level of the battery liquid in the housing in this way, the user can visually check the operating state of the light emitting diode to determine the liquid level of the battery liquid in the housing. Can be confirmed from the outside. Therefore, it is possible to save the trouble of opening the plug of the storage battery when checking the liquid level of the battery liquid.
