I am having problems with my Zebralight which I have only owned approx 2 mos. It has never been used hard (outdoors etc) and mainly used as a nightlight, now it doesnt work at all. Ive cleaned the threads, contacts, changed batteries etc. and it does nothing, no light whatsoever. Any else have similar problems, or ideas appreciated. I emailed Zebralight refrence problem but havent heard back yet. When it works its a wonderful light.
