Greetings,

My 5yr is learning the violin and his teacher says he'll soon be capable of playing a simple star wars song soon. I want to build him a "bow saber", ie. light up his violin bow like a light saber. His bow is only 18" long. My goal is make this as light weight as possible as additional weight will effect his playing.

I've looked at using an LED string (which seems like the most common approach for bow sabers)--but wondering is some sort of lightweight diffuse tubing would allow me fewer LEDs and thus less weight.

I have basic electronic knowledge and can solder decently.

Suggestions?
