the maths is right, but its applied wrong, as its not the 12V side thats going to cause any problem, you can touch and lick that all day long (though licking may cook your taste buds), its the HV side that has the potential to cause a problem (but as per your previous post its all sealed up with and well rated cable) the amps there will be milliamps but I would argue it only takes milliamps to kill.It takes 0.5 -0.7 amps to kill ...
w = v x a so a 35w one should draw 2.91 amps haha correct me if im wrong ....
But yeah as agreed theres no point doing the maths as the to get the shock you'd pretty much have to be trying.
