Backlit signs are illuminated displays that use light sources behind the sign material to enhance visibility and attract attention. Commonly made from materials like acrylic or vinyl, these signs are often used in commercial settings, such as storefronts and restaurants, to promote brands or convey information. The lighting can be achieved through various methods, including LED or fluorescent bulbs, which provide even illumination. Backlit signs are effective both day and night, making them a popular choice for businesses looking to enhance their visibility and appeal to customers, especially in busy urban areas.
