I bought two of the Ikea clip-on lights like Peckish mentioned and clipped them to the arms of my longarm. They work great, in addition to the light that is already on the longarm and the overhead light bar. It takes a lot of light to see those stitches! For my sewing machine, the Bernina's light is usually good enough, but when I need more light I have a desk light with natural light bulbs and I like that better than a stick-on light.
