Mk 147 voltage

Hi all,
I was just wondering if anybody knows what would have to be changed on the MK147 kit to allow it to be used with a 12v supply?

Thanks

Should work fine on 12V (exactly 12V, not higher…)

Hmmm, may fluctuate a little as I was thinking a car. Could possibly peak at 14.4v so what would you suggest??

Thanks
Craig

Increase led series resistor slightly. Sorry, no values, please experiment.

Sorry, which one of them is that?

R7…
