[Suggestion] Self-illuminating exit (and other such) signage

[sinsinewave]

Explain your idea

self-illuminating signage using glowsquid ink would be a great addition to the recent decorations; specifically in the style of, for example, industrial/commercial emergency exit signs; details such as those are quite helpful in factory buildings for grounding the design to reality, and, well, immersion

this would also complement vanilla by giving uses to the relatively pointless glowsquids
