Did you buy a string of 220V small lights? If so, then you can treat each lantern as a light bulb with a rated voltage of 220 V.

There are many small bulbs on each lantern, but each lantern has only one external connector, which is generally required to be connected to the 220V lighting circuit, so the lanterns should be connected in parallel to the circuit.

That is, one line is the fire line, one line is the zero line, and then there are colored lights in the street. Just like light bulbs at home, each one is connected to a 220V circuit.
