太陽電池が使用されていた。2. Description of the Related Art Various safety devices such as a breaker are generally installed at railroad crossings in order to ensure the safety of trains and pedestrians crossing the railroad crossings. The crossing gate is generally provided with a railroad crossing pole that opens and closes as a train passes or approaches. In addition to the railroad crossing pole, a light-emitting body such as an LED is additionally provided to draw the attention of passersby. There is also a place where a so-called self-luminous railroad crossing safety device is installed, which is attached to a railroad crossing pole or a marker plate of a pillar to light or blink the light emitting body. Conventionally, a commercial power source or a solar cell has been used as the power source of the light emitting body.
