These headlights are made from prewired 0402 or 0603 LEDs, 1.5mm (0.06") diameter fiber optic rod and 1/32" 2:1 ratio heat shrink tubing. The LED lead wires are bent so the LED faces outward away from the wires then a short length of shrink tubing is slipped over the LED. A short length of fiber optic rod is cut and inserted into the shrink tubing pressed against the LED face. When the assembly is held near a flame for a moment the tubing shrinks and secures the fiber optic rod to the LED. The outer face of the fiber optic rod is then polished.
