(b) 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.

An object, material, or covering that alters the headlamp’s visibility from at least 450 feet for an uppermost distribution of light or at least 150 feet for a lowermost distribution of light may not be placed, displayed, installed, affixed, or applied over a headlamp.

Said 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.
(3) A violation of this section is a noncriminal traffic infraction, punishable as a nonmoving violation as provided in chapter 318.
