So, here is what I would do.
For the bulbs on the hat and tail, you are actually going to get clear plastic bottles of appropriate shape/size. The ones on the feet, being round, you can probably do with clear plastic christmas ornaments intended for crafting and do the same. Tint these to the amber color you need, there are a couple of different ways to do that, look them up.
The good news is that you don't need to see through them for visibility purposes like a visor, so you can use methods that end up making light a little blurry and still be fine. For your purpose, I think the easiest way is a mixture of food coloring and elmers glue painted on the inside in a thin layer.
Then. you use wire to make the 'filament' inside of the bottle-bulbs.
For the upper arm sleeves, then, what you do is that you have a dark cloth sleeve that actually covers your arms, with wire to make a "flat" version of the filament design that is glued to/printed on the arm sleeve. So the filament is a brighter distinct shape on the dark colored sleeve, drawing the eye.
Then, you use a clear plastic to make the 'puff' part and tint it like you did the bottles, designed to go over the sleeve and cover it/connect with the shoulder. This will give the effect of the shoulder being visually very similar to the bulbs, including a filament, the only difference is that there isn't empty space between the filament and your torso.
Thats the best solution I can think of.
