Its flickering after only a year - INFORCE Multifunction Weapon Mounted White/IR Light

Roughly only a year later with little use, it started flickering. I changed the battery and same thing. I've used the rifle many times with it hooked up, but I rarely use the light. This is pretty disappointing considering the short time I've had it and the lack of use in terms of using the light. I guess now I have to spend twice as much for a different light.
