I had not had my Featherweight (the first one) very long when the light bulb burned out. (I am sure it was the original bulb.) I went down to the local store for a replacement part. The gentleman there told me that they didn't make 15 watt bulbs anymore and that I would have better light with the 25 watt bulb he had in stock. This is simply not true, and a 25 watt bulb can lead to some heat expansion problems for you and your beloved machine. So, replace the bulb with a 15 watt bulb as the engineers who designed the Featherweights intended.
