why aren't my christmas lights working

Oh no, it sounds like your Christmas lights aren't working. Don't worry, there are a few things we can try to fix the problem. First, let's check the power source. Is the outlet turned on? Is the extension cord plugged in properly? If so, we can move on to checking the lights themselves. Are any of the bulbs burnt out or broken? If so, we can replace them. We can also try swapping out the extension cord, just to rule out any wiring issues.
