I just got mine the other day. When I first put batteries in it and turned it on I was happy to see they did away with that annoying blinking mode. It went from high intensity to low to off. I took the light out hunting last night and 10 minutes into my first set the high setting became the blink setting. The light now goes blink, low, off. Is that a sign of the batteries going dead or is there a setting that can be adjusted? Not alot of instructions came with the light.
