I am in the middle of making a tail that has vinyl tubing in it. Then I have a box of glow necklaces. The kids you get at fairs. Then I can slide the necklaces into the tubing to give glow in the dark of whatever color I like. Then I can switch them out next time. If you want to do what I think you are saying you can sew or glue the tubing on where you want the glowing to be and use the necklace technique.
