Ah, I'm glad you asked! Christmas lights are a wonderful addition to any holiday decor, and they're not too difficult to set up. You can start by finding an outlet with enough space to plug in the lights. Then, simply plug the lights into the outlet and make sure the switch is turned on. If you're using an extension cord, make sure to plug it into the outlet before plugging in the lights. You should then be all set to enjoy your Christmas lights!
