I noticed this morning, much to my chagrin, that my ARC AAA was flickering when I turned it on. Not going completely out, but marked and fairly rapid fluctuation in light output. I tried wiping off the threads of the head, abrading the ends of the battery, and finally taking a small flat-bladed screwdriver and scraping the contact on the bottom of the head and the little nipple that contacts the negative end of the battery. The last step seemed to cure the flickering problem. I'm going to keep an eye on that little bugger for the next few days.
