Well, Christmas lights are a really fun way to add some festive cheer to your home. The first step is to choose the type of lights you want. You can go with traditional incandescent lights, which are the most common type. Or you can choose LED lights, which are more energy-efficient and last longer. Once you've decided on your lights, you'll need to make sure you have enough outlets or extension cords to plug them in. Then, you'll need to figure out where you want to hang them. I'd recommend starting at the top of your house and working your way down.
