It is also possible to adopt methods that utilize solar energy. In this case, it is desirable to adopt a power supply switching system to prevent the necessary luminescence from being obtained due to power shortages due to rain, etc. Please note that the installation depends on the height of the main power transmission tower. However, in this case, it is also possible to incorporate a pulse circuit into the circuit on the printed wiring board to cause the light to flicker.
