Fisher is correct. If you read up on led lights, there are different quality of led lamps and they are effected greatly by a number of things like voltage, temperature, amperage. If the manufacturer builds the lights and over drives them, pushes the max voltage and/or amperage, their life is greatly diminished. If they are soldered to the pc board, you may be able to find a friend to rebuild them with a higher quality led. Good Luck.
