how are christmas tree lights wired

Christmas tree lights are typically wired in parallel circuits, which means that each bulb has its own circuit and can be controlled independently. This allows for easy troubleshooting in case one bulb burns out, as only that bulb will be affected. Additionally, parallel circuits are more efficient than series circuits, as they allow for the maximum amount of current to flow through each bulb. This means that more lights can be added to a single tree without overloading the circuit. The lights are typically powered by an outlet and connected to the tree via a wiring harness.
