A lightbox sign is a type of signage that uses internal lighting, usually LED, to illuminate the design or logo on the face of the sign. The light shines through a translucent panel, creating a soft glow that's visible in daylight and after dark. Lightbox signs are commonly used for attracting attention without being over the top, especially in lower-light environments or during early morning and evening hours. They are made from materials that allow light to diffuse evenly, such as acrylic or polycarbonate, and are rust-proof, weather-resistant, and easy to install.
