…
(7) Headlamps arranged to provide a single distribution of light not supplemented by auxiliary

1939, in lieu of multiple-beam road-lighting equipment, if the single distribution of light
complies with the following requirements and limitations:
(a) The headlamps shall be so aimed that when the vehicle is not loaded none of the
high intensity portion of the light shall, at a distance of twenty-five (25) feet ahead,
project higher than a level of five (5) inches below the level of the center of the light
from which it comes, and in no case higher than forty-two (42) inches above the level on
which the vehicle stands, at a distance of seventy-five (75) feet ahead;
(b) The intensity shall be sufficient to reveal persons and vehicles at a distance of at
least two hundred (200) feet; and
(c) Whenever the operator of a motor vehicle approaches an oncoming vehicle within
five hundred (500) feet, he shall use a distribution of light or composite beam so aimed
that the glaring rays are not projected into the eyes of the oncoming driver. In no case
shall the high intensity portion which is projected to the left of the prolongation of the
extreme left side of the vehicle be aimed higher than the center of the lamp from which
it comes at a distance of twenty-five (25) feet ahead, and in no case higher than a level
of forty-two (42) inches above the level upon which the vehicle stands at a distance of
seventy-five (75) feet ahead.
