    Driver to power another driver

    Ok, this isnt for a pacific bike light..
    I have an old dive light that has a driver that has a mosfet and one of those buzzer things so im told..
    The switch is pushed and the light comes on, but the switch springs back to it's original position, repeat to turn the light off.

    So question is as this driver has something unique for the switch it has, is there any reason why i couldnt wire the driver to one of quazzles drivers?

    Even if you can, you will be doubling the driver-based power loss. None are 100% efficient. A problem may arise because most drivers work off a constant voltage source and output a constant current.

    Unless you need the "buzzer things", you may want to look for a driver that operates with a momentary switch. From what I understand, the only downside to those type drivers is that there is a small amount trickle current that will slowly discharge your battery when it is off - you would have to pull the battery.
