If you own this model Singer, where on earth is the light bulb?? This is my daughter's machine and it is so dark without a floor lamp next to it. I can not find a place for a bulb. I went on line to buy a presser foot lever and saw that there was a light bulb available. Hmmm, that means, somewhere there is a blown out bulb. Any info would be appreciated...a photo of the location would be fabulous!
