Ready to wrap! Wire inserted into wrapping tool and

Before and after shots of LED fiber optic assembly. NOTE:
You can use either a low-wattage soldering iron or hair-dryer set on ‘low’ to shrink tubing. The Resident Mad Scientist used a soldering iron to shrink first the LED end, then the fiber end, giving
greatest control over keeping the optical fibers touching the LED bulb for best light quality.
