You can also find these bayonet (This is what they are called) type bulbs at Hancock's and some hardware stores. Be sure to check the wattage on your old bulb, before purchasing just one that looks like yours. I'm not sure but I think Hobby Lobby has some, and perhaps even Harbor Freight. You need to take your old bulb with you to be sure you are getting the right size on the end that goes into the machine. Some are short and fat or squatty, then some are long and slender. Some Quilt shops carry them.
