The statement that a series street light circuit is worked as a high voltage circuit for safety purposes is true. In a series circuit, the same current flows through all components, and if one light fails, the others will not operate, isolating the fault. This setup can be advantageous because it reduces the total current required for operation, which can limit heat generation and minimize the risk of fire.

Additionally, operating street lights at higher voltages allows for a more efficient transmission of electricity over longer distances, ultimately reducing the losses that occur when electricity travels through conductors. However, high voltage can pose significant safety risks to workers and the public, necessitating specific safety protocols during installation and maintenance. Because of these heightened safety protocols and careful design considerations, the assertion that a series street light circuit operates at high voltage for safety purposes holds validity.
