A structure is provided that is at least partially adhered by a light-curable adhesive. The structure includes first and second structural components disposed in a facing relationship. The structure also includes a light-curable adhesive impregnated within at least one of the first and second structural components or disposed between the first and second structural components. The structure of this example embodiment further includes one or more side-emitting light guiding members, such as side-emitting optical fibers, positioned between the first and second structural components and in communication with the light-curable adhesive. The one or more side-emitting light guiding members are configured to emit light along a length of the one or more side-emitting light guiding members. Corresponding methods to assemble the structure and to cure the light-curable adhesive within the structure are also provided.
