how are xmas lights wired

Christmas lights are wired in a parallel circuit, which means that all the lights are connected together, allowing them to operate independently. Each bulb has its own filament or wire that conducts electricity. The wires are connected to a power source, such as a wall outlet or battery pack, and the electricity flows through the circuit, lighting up each bulb. In parallel circuits, if one bulb burns out or is removed, the rest of the lights will still work, making them a reliable choice for decorating your home or Christmas tree.
