§ 9.44.230. Multiple beam road lighting equipment required.

A.

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

1.

There shall be an uppermost distribution of light, or composite beam, so aimed and of such intensity to reveal persons and vehicles at a distance of at least 450 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 150 feet ahead, and on a straight, level road 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.

B.

Every motor vehicle which has multiple beam road lighting equipment shall be equipped with a beam indicator, which shall be lighted whenever the uppermost distribution of light from the headlamps is in use, and shall not otherwise be lighted. The indicator shall be so designed and located that when lighted it will be readily visible without glare to the driver of the vehicle so equipped.
