Product review (5 stars): Very easy to install!
Somehow the previous owner of the house dealt with no light in the refrigerator.  I replaced the bulb, and when that didn't work, I figured it was the switch.  Ordered this, and had replaced it in under a minute.  LET THERE BE LIGHT!  I can finally see the leftovers, so they don't get forgotten about in the back of the fridge!
