The battery is the original I just can't belive it made it this long it is 6 years old going on 7! The longest lasting battery I have ever had only made 5 years! What is the longest battery life you have seen and what brand was it?

My lights were doing similar things and the problem was in the connectors. They actually melted the plastic housing causing loose connections which caused them to change from dim to bright to off. Good luck
