Illumination changes what a sign can do after the lights dim. The Edge Tower Backlit Signage System takes the double-sided Edge Tower and adds LED edge-to-edge backlighting, turning both graphic faces into evenly lit panels that read across a dark or dramatic space — an evening event floor, a dim corridor, a high-impact entrance. Everything else carries over from the non-backlit tower: freestanding placement, 360-degree double-sided visibility, mobility for repositioning, and quick-change panels for fast re-messaging. Where the ambient light is ordinary, the standard Edge Tower Sign Stand covers the same job unlit.
