Who was it asking about when did the 99 become electrified? As far as I can find out, the first electric 99 was the 99-13 which was manufactured starting in 1924.

It was me!!! I just bought a 1924 Singer 99 that has the foot petal and is in a bentwood case. It doesn't have a light. When were lights first put on the Singers, any one know? The wiring has been replaced, but the foot petal is the big old metal one. I also have a 1928 Singer 99-13 in the bentwood case, and it has the knee bar and also a light. Other than that, they are similar. I had been looking in the serial numbers and where I looked, the single letter ones don't tell the model of the machines. The AA ones do, and that's where my 1924 Singer 99 is listed, in the first group of 99's . Maybe some were the plain electrified 99's and others were the 99-13s. That is so exciting to me!!! Ya, I know some of the silliest things excite me. Thanks Nancy.
