Product review (5 stars): Works great
I did not have a light in my icemaker for the last almost 10 years since we purchased our fridge.  I didn't care about it too much but we often have an issue with the water lines freezing up every winter and we have to thaw it out with blow drier and such.  We had an issue with the whole unit and had to call the sears repair man and he suggested getting this bulb to warm up the water lines a little bit from the heat generated from it coming on each time.  Makes sense, so far so good.  Hopefully it will help with my waterline freezing issue. I posted this review hoping it will help someone else with the same problem.
