What Is A Custom Wall Light Sign?
A custom wall light sign for wall decor refers to a sign that is either painted on or mounted flush against the exterior of a building, extending no more than 12 inches outward from the surface. These custom wall light signs must be secured exclusively to flat, opaque walls. Additionally, no custom wall led sign for wall decor should extend beyond half its height above the top edge of the wall it is attached to—otherwise, it would be classified as a Roof Sign.
