36 Neon Signs by Sims Urbania
The signs are $75 and can be found in Deco –> Paintings. They do not cast light, but have a nice glow as you can see from the pictures. To place them in windows, you’ll need to use the “moveobjects on” cheat. Signs will shift up and down the wall if you have AL.
I think the original describtions says pretty much everything.
