how led christmas lights are wired

I'm glad you asked! Christmas lights are typically wired in a series connection, which means that the electricity flows through each bulb in turn. This is a simple and effective way to connect lights, but it can also be a bit of a safety hazard. If one bulb breaks, it can cause the whole string of lights to go out. A better alternative is to use a parallel connection, where the bulbs are wired in pairs and the electricity flows through both at the same time. This is a more complicated setup, but it's also much safer.
