Except as otherwise provided in this article, the headlamps, the auxiliary driving lamp or the auxiliary passing lamp or combinations of the headlamps, driving lamp or passing lamp on a motor vehicle other than a motor driven cycle shall be arranged so that selection may be made between distributions of light projected to different elevations, subject to the following requirements and limitations:

1. There shall 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 three hundred fifty feet ahead for all conditions of loading.

2. There shall 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 feet ahead, and under any condition of loading, none of the high intensity portion of the beam shall be directed to strike the eyes of an approaching driver.

3. A new motor vehicle, other than a motor driven cycle or a fully autonomous vehicle incapable of operation by a human driver, that is registered in this state and that has multiple beam road lighting equipment shall be equipped with a beam indicator that is:

(a)Lighted when the uppermost distribution of light from the headlamps is in use and not otherwise lighted.

(b)Designed and located so that when lighted it is readily visible without glare to the driver of the vehicle.

4. A person shall not operate a motor vehicle with a colored transparent or translucent substance or material installed, affixed or applied on or in front of the headlamps, the auxiliary driving lamp or the auxiliary passing lamp or combinations of the headlamps, driving lamp or passing lamp that would obstruct, reduce or interfere with the visibility or effectiveness of the headlamps or that would change the color of light emitted.
