    help put my light back together!

    please dumb things down as much as possible. Electronics is not my forte by any means.

    I have a few of these cheap ebay lights that are functional and bright, but not very reliable. the LED is an cree xml. i cut the wires when the switch completely stopped working. all i would get is a dim mode. no on off function. it was either "on dim" when plugged in or "off" when unplugged.

    To my knowledge the led is still in good shape. The battery packs are fine. I assume what i need to replace is the switch/chip? can someone give me some guidance what i can buy to replace it.

    The Chinese lights I have repaired both had bad driver boards. Based on the symptom you describe, my guess is your driver board is bad, not the switch. Look for obviously burned components and broken connections. Beyond that go to dealextreme or kaidomain and try to find a similar driver board. Your best bet would be to chuck it and buy a new lighthead.

    Was going to repair my board after blowing it with a battery pack I wired backwards. At $4.30 it was cheaper to replace the board with this than the shipping costs for a couple of ICs.

    The battery indicator glows blue instead of green. With a scc p7 it draws 1.08 amp @ 8.0 volts off the power supply at work so I think it delivers more that the 1500ma DX specs on their page.

    These lights are so cheap they are pretty much disposable. You could just get a new head for $17 or even upgrade to a dual/triple xml t6 headlamp
