I finally broke down and bought a nice light for my bike. When I got it I followed the instructions to a T as far as the battery goes to hopefully extend the life. I turned the light on and let it burn almost all the way down so the light was dim, then recharged it with no problems. Everything worked fine and the light worked like it is supposed to. I turned it on so it would drain the battery but got on the phone and forgot about it and the battery got so low that it wouldn't turn the light on. The instructions say to let the light get dim but not to go all the way off. I recharged it again (this was the second time if you're keeping score at home) and when I plugged it in to check it I got nothing. I unplugged everything and let it sit for a while then replugged it in and one beam came on. When I pushed the button to go to two beams I had nothing. I unplugged everything again, let it sit, then replugged it all together and I got a quick flicker from one bulb then nothing. Now I'm getting nothing and really bummed.

Any suggestions to what is going on? The date of manufacture on the box is 10/05/2005 and I got it in late November.
