Hmmm…maybe it shorted out? I’d try contacting the manufacturer of the LED upgrade. FYI, I HIGHLY recommend the AA 3 watt LED Maglites. I have both, and the 3 watt is MUCH brighter than the dimmer “upgrade kits”. They’re a great buy for the price. I tested mine and it ran for over 4 hours on a set of batteries, so it doesn’t drain the power very fast. I use rechargables for mine, and I even have a solar battery charger so I can charge them in the wilderness if I wanted. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
