Thanks so much to everyone for their reviews and helps in finding great led strips. I especially would like them for my antique Singer machines that I collect, plus some of just slightly older ones with only an incandescent bulb. I did finally find out that the clear sewing feet- especially the 1/4” ones did not help me at all - got shadows that confused my wacky eyes (yes, they are truly wacky!!!). So I stick with the metal ones. I definitely will be checking all the different links. The ones from Insight are inly $30.
