Can the line be seen behind the lamp head? It is recommended to get electricity from the line behind the lamp head. If there is electricity 24 hours a day, you need someone to stand on a wooden stool, put on plastic gloves (or double-layered white gloves for labor), and then use a knife or something like that. Break open two holes for both the live wire and the neutral wire, wrap the prepared wires first with the neutral wire and then with the live wire, and wrap them with insulating tape (note: be sure to wrap the neutral wire first, and then wrap it with insulating tape) Wrap live wires, that is to say, two wires must not be constructed at the same time. People are safe if there is no loop). The electricity you take out must be connected to a switch in advance to facilitate your own control.
