Red Light for Fridge

So I don't freakin go night blind every time I get up to get some juice at night, I want a switch on the outside of the fridge that I can flip to make the main fridge light go off and a red light inside go on. Could be even easier, just turn the intensity of the light already in there down to a minimum. Has to be from the outside though, or perhaps be put on a timer so it happens at night and not in the day.
