When you have the correct scale and fit for your aluminum reflector, pull the electrical shrink wrap tubing up over your wires as far as they will go. This will form the extension cord. Now pull a ½ inch long wider piece of black tubing up over the extension cord piece to the base of the LED, covering the wider resistors in the wire below the LED base. Tuck the base of your light reflector into the top of the black shrink tubing. Trim the tubing if necessary, and use a hair dryer or heat gun, to shrink the tubing from where it joins the LED down to the end of the tubing.
