Light Bulbs for Sewing Machines Push-In Base and Screw-In DRITZ and Singer Sewing Machine light bulbs are offered. These bulbs are often regarded as universal, and they are compatible with the majority of devices. However, not all bulb types may be interchangeable with certain models of sewing machines. Sewing machine light bulbs are easy to replace and usually only take a few minutes. Before you start, make sure that you remove the original plug from the wall outlet to prevent any electrical damage. Then, find the right size screwdriver and remove the four screws that hold the base of the old bulb in place. Finally, pull out the old filament coil and put in the new one. If necessary, use a small piece of wire to connect the two ends of the coil to complete their circuit. Although most sewing machine light bulbs are interchangeable, some specific models may have parts that fit only inside their respective manufacturer's lamp housings. If you have problems finding suitable replacements, consider buying a new sewing machine lamp housing. Note that some special lamps cannot be used with new lamp housings; we recommend that you avoid these models. The type of sewing machine light bulb you need depends on how much light you want to get from your machine. If you only need to see the needle position, try using a DRITZ or Singer sewing machine light bulb.
