Illuminated signs are visual displays that use light to enhance visibility and attract attention. Commonly found in urban areas, these signs can be made from various materials, including plastic, metal, and glass. They often feature bright colors and can be powered by electricity or solar energy, making them effective for advertising and wayfinding. These signs come in different forms, such as neon signs, LED displays, and backlit panels. They are widely used by businesses, such as restaurants and retail stores, to promote their services and products, especially during nighttime when visibility is crucial.
