Replacement "push-in" style LIGHT BULB for the Singer Featherweight 221 and 222K as well as many other vintage Singer models. Be sure to watch our video below for how to easily change a light bulb on your Singer Featherweight. 110 volt = North American (USA, Canada, etc.) Electrical Current 220 volt = Great Britain, Europe, Australia and most of the entire world Special Note: If you have are using a machine with a voltage converter, you will need to order the light bulb that accommodates the machine prior to conversion. For example, if you are using a machine that converts its original 220 voltage to 110 voltage, so you can plug it into the wall here in the USA, then you will need a 220 volt light bulb. However, if you are traveling abroad with your 110 voltage machine and you have a converter box which allows you to plug it into the 220 electrical current in another country, like Great Britain, then you will need a 110 volt light bulb. Be sure to check out our video, under the video tab, on how to change the light bulb.
