Product review (5 stars): These are like your car headlight bulbs
DON"T TOUCH THE GLASS!!!!!!!  These are like your car headlight bulbs; any oil from your fingers causes the glass to crack and immediately burn out!  Although they are very difficult to install in the GE fridge door dispenser, I simply used a pair of nitrile disposable gloves which gives you a really good grip on the bulb for installation.  Easy Peasy...
