When/Where did you buy the machine. Most machines these days only have a 90 warranty. Janome has a bit longer... then of course there's the warranty the seller may or may not sell you.

Personally? I would toss that Singer as far as I could then let the neighbor boys shoot at it. I'm sorry they just aren't made like they used to be and Singer is not well regarded by seamers anymore. Spend your $$$$ on a Janome or Babylock.

Most likely, the light has burnt out. It's probably a type of appliance bulb. Take a look in your machine's manual and see if it tells you what type of light to buy. If it does, take the manual with you to the hardware store, too (preferably an Ace, True Value, something like that-not Home Depot). Otherwise, take the bulb with you and ask someone at the store for help. Tell them what the bulb is for and they should be able to help you buy a replacement.

Sewing machines use standard appliance bulbs, but they are very low watt bulbs and not just a general type, so be sure to get some help. You're bulb just probably has burnt out just like one in your lamp does.
