Some of the items you will need are white LEDs,1/16 copper or brass K&S tubing, some small insulated or enameled wire that fits in the tube, and a battery pack to test it with. You can use 3mm or 5mm LEDs or "golden white" LEDs if you can afford them or the price drops. You can also make some nice looking shades using cup washers from the hardware store. Use the #4 washers for 3mm and #6 for 5mm LEDs. You will also need a soldering iron, flux, and solder along with common modeling items such as a 1/16" drill bit, hobby or snapblade knife, gel CA, paints, and whiteglue.
