What you need for a 36 volt to 12 volt is a voltage regular
they are about $60 on ebay
if you try to go off of just one set of batteries the resistance when charging will make that bank of batteries weak and will fail prematurely
I did this with some small led's (2x .02 amp draw)in my battery room and after about 3 months that set of batteries were weak to the point I had to take them off-line
rather pay $60 instead of the price of a new set of batteries
I don't see this affecting a golf cart, the light will be switched off during charging.
