That's a good question! While it's rare, there is always the possibility of a fire risk with any type of electrical equipment, including Christmas lights. Overloading electrical outlets, using damaged or faulty lights, or using too many lights at once can all increase the risk of a fire. To reduce the risk, it's important to follow the manufacturer's instructions when using and storing your lights. Additionally, you should always inspect your lights for any damage before using them and keep them away from flammable materials like curtains, paper, or fabric.
