What can I do to fix this rear light? This light unable to light up, I checked it not a problem of battery, is it the light burnt-out of circuit broken? I bought it and used it with in half year, is it not really durable or I use a wrong way to maintain it? If I know the cause of error I would do something prevent it happen

  1. Causes I have encountered for this:

    * Battery empty (which you rule out)
    * Contacts corroded (the metal things that touch the battery). So scratch these a bit.
    * Contacts deformed (don’t touch the battery anymore). So bend them back into position.
    * Circuit broken (if it’s that, it should still be under warranty)

    That’s what I know of. Maybe there are other reasons.
