how many christmas lights can string together

Oh, that's a good one! Let's see...... based on the average wattage of a Christmas light and the voltage supplied by a typical outlet, we could probably string together tens of thousands of lights before the wires get overloaded. Of course, it's always best to check the manufacturer's specifications to ensure safety and proper usage. But in theory, we could create a dazzling display of lights that could span several city blocks!
