Pretty close to zero

A lot - that's why there is a fuse
Another way to look at it - what would happen if you ran a plain copper wire from positive to negative?
It would melt - especially if it you used a Li-on battery
Regarding the 12v bulbs on the Dong Fang: it doesn't matter whether the current is AC or DC
But if I tried to directly connect an LED headlight in place of the incandescent bulbs they would work properly.
BTW I am running LED's for the turn signals, using an LED flasher

I really have no idea what you're trying to communicate. It does matter if it's ac or dc, almost all 12v LED bulbs do not work off an AC current, or at best will flicker since it's only working 1/2 the time.
