A system can combine edgelit signage and edgelit illumination. The system can comprise two edgelit lightguide sections, one supporting signage and another supporting illumination. The lightguide section that supports signage can comprise a backlit face inscribed with text or graphics conveying an emergency message. The lightguide section that supports illumination can comprise a face patterned with features that release light, for example for emergency illumination. The two lightguide sections can be two areas of a single edgelit lightguide. The two lightguide sections can alternatively formed from two separate lightguides. In some examples, one or more illumination lightguide sections can be configured as a trim plate.
