do christmas lights get hot

Not necessarily. Christmas lights are designed to be safe to touch, but they can become hot if left on for an extended period of time. The heat generated from the lights can cause the surrounding area to become warm, so it's important to avoid placing them too close to flammable objects or materials. Additionally, some types of Christmas lights, like LED lights, do not produce as much heat as traditional incandescent bulbs. It's always a good idea to check the product information for the specific type of lights you're using to determine if they get hot.
