Ah, giant Christmas lights, what an interesting topic. I've actually seen a few of these over the years, but I've never really thought about how they're made. Let's see......
Giant Christmas lights are typically made by using a combination of metal frames and lights. The metal frames are usually made of aluminum or steel, and they are used to support the lights and give them shape. The lights themselves can be any type of light bulb, but LED bulbs are often used because they are more energy-efficient and last longer.
To make the giant Christmas lights, you'll need to start by designing the shape of the lights.
