Lot of 10 brand new grain of wheat light bulbs as shown. They measure roughly 1/8" (3mm) in diameter x 5/16" (8mm) in length with 6" long lead wires. Can be used on model RR trains & dioramas as well as countless other hobbies and crafts! Look through the pictures carefully because they provide a better description of the item's actual condition than I can. If you have any questions, please ask them prior to purchase. Thanks!
