can christmas lights cause fires

"Christmas lights can indeed cause fires if they're not used properly or if they're faulty. It's important to follow the manufacturer's instructions and only use lights that have been tested and certified by a reputable organization like UL or CSA. Make sure to inspect your lights for any signs of damage before using them, and never leave them unattended while they're plugged in. It's also a good idea to turn off your lights when you leave the house or go to sleep."
