The utility model provides a novel light string, electric wire body including the lamp cluster, the electric wire body includes insulating cortex and is located the inside conductive filament of insulating cortex, the electric wire body still includes metal reinforcing article, metal reinforcing article lies in inside the conductive filament. The beneficial effects of the utility model are that the pulling force that uses the trade was used christmas that this novel electric wire made single line light cluster can improve the lamp cluster saves the subordinate line, saves cost of labor and material cost.
