Can someone tell me what size fuse goes in the lights on an H. I can't read the fine print on the one I have. Does it matter if its 12 volts?

IMHO a fuse doesn't care about volts, it only measures amps. A 10amp fuse will carry if 6 volts 6X10 60 watts. if 12 volt 12X10 = 120 watts.
 
All those 6 volts old tractors used a 20 amp fuse. When they went 12 volts they dropped down to 10 amps. Voltage is pretty much irrelevant unless used in high voltage situations where insulation breakdown of the fuse would come into play.
