@jgonzalez nice shapes! curves are wickedly easy for wires, great job on that.
As for emision: I would just stick a Point Light in it. If you want to see a bulb you can also stick a sphere in it with just a simple emissive material (just use an emission node instead of principled shader), but if you’re using Eevee that alone won’t work well so you have to use both the point light and the emissive sphere, but if you’re using Cycles you’re settled with just an emissive sphere. And maybe make the glass material transparent and play with the roughness and such. SSS won’t help you here, that’s something for human skin and leaves…
Things like transparency and SSS are all build into the principled shader so playing with those sliders can get you some nice quick results. Fun to experiment with! This is a great tutorial on all it’s features.
Hope this helps..
