What is the light switch position on a 33? Is the off in the center? what is on the left and on the right of the center position? I read in a prior post about 36s that "the center its off, to the right the high beam light comes on and to left from off position the first position is the park lights and second is low beam". Can somebody clarify the correct position for 1933? Thanks !! Manuel
