how do you make a led's light extend? Answered
As in, I have a flash drive that I want to steampunk and thought about putting a falseto vacuum tube on the end that the filament lights up when I plug it in. What is the most efficient way to transfer the light from the led to light up the false filament. (My led is an orngeish amber color.) Would it have to be like a fiber optic or a small tube filled with glue?
