Except as hereinafter provided, the headlamps or the auxiliary driving lamp or the auxiliary 
passing lamp or combination thereof on motor vehicles must be so arranged that the driver may 
select at will between distributions of light projected to different elevations and these lamps may, 
in addition, be so arranged that selection can be made automatically, subject to the following 
limitations:

1. There must be an uppermost distribution of light, or composite beam, so aimed and of 
sufficient intensity to reveal persons and vehicles at a distance of at least four hundred 
fifty feet [137.16 meters] ahead for all conditions of loading.
2. There must be a lowermost distribution of light, or composite beam, so aimed and of 
sufficient intensity to reveal persons and vehicles at a distance of at least one hundred 
fifty feet [45.72 meters] ahead; and on a straight level road under any condition of 
loading none of the high -intensity portion of the beam may be directed to strike the 
eyes of an approaching driver.
3. Every new motor vehicle, registered in this state, which has multiple -beam 
road-lighting equipment must be equipped with a beam indicator, which must be 
lighted whenever the uppermost distribution of light from the headlamps is in use, and 
may not otherwise be lighted. The indicator must be so designed and located that 
when lighted it will be readily visible without glare to the driver of the vehicle so 
equipped.
