Working on a project, and realized that whatever my dog’s light-up dog collar is made from would be perfect for the lighting effect I want here. It might also be another way to fake neon-tube style lighting.
The one small LED makes the whole thing glow. It’s essentially an edge-lit, solid, flexible tube. Product pages just say “silicon tube”, but I’m not seeing anything similar looking when I search. I could get away with buying several dog collars, but I would rather just buy a roll of the material not be limited by the LED/Battery component of the collar.
If someone has a keyword to search with other than “solid silicon tube”, or even better a source for this material, I would love to know.
