    Troubleshooting DX Cree light

    Bought one of the DX lights for an 18 hour race. This one:

    Buy ZXC-01 Cree XM-L T6 910lm 3-Mode Memory White Bike Light - Black (4 x 18650)

    Worked fine for a week, now I can't get it to work. I plug it in and it shows fully charged, and a check with a volt meter shows full charge. When I plug it into the light, The on/off button shows red (signaling dead battery) and it will only give me one level of light rather than three.

    Can anybody suggest what's wrong and what I might do to fix? Out of the return policy I'm afraid.

    Thanks much.

    You may have to open up your light to see if there are any loose wires inside. Or if you have a buddy that you can plug your battery into to see if it'll light up. You'll know it's not the battery if it does.

    Most likely a bad driver in the light head. Like Pucked says open it and look for broken wires or obviously burned components. If there is an inductor on the driver (donut shaped thing with coils of wire wrapped around it), check closely for where those wires solder to the board. I've seen that before. Otherwise you might need to order a new board. Or maybe another light.
