A pre-lit Christmas tree is a type of artificial Christmas tree that comes with pre-installed lights, saving you the hassle of having to decorate it with lights yourself. These trees typically feature a combination of built-in lights, ranging from simple white lights to colorful LED lights. The lights are usually controlled by a single switch or remote control, allowing you to easily turn them on and off. Pre-lit Christmas trees come in a variety of styles, sizes, and colors, making it easy to find one that fits your home decor and holiday theme.
