    They should work but intensity will vary, they are generally series groups of 3 LEDs with a limiting resistor... And most are balanced for a nominal 12V voltage... There is always the chance they won't work at less Voltage, but the slight over voltage won't be as big of an issue, they will work but be slightly overdriven...

    BTW a 12V vehicle battery is 'dead' at 12V, it should never be bellow 12V certainly not 10V...

    Thanks, yes.
    The LED will not be connected at the battery.
    It will be connected at some wires where together with other loads there will be a voltage drop.

    Practical experience anyone?
