A. 
"When lighted lamps are required" means at any time from a one-half (1/2) hour after sunset to one-half (1/2) hour before sunrise and at any other time when there is not sufficient light to render clearly discernible persons and vehicles on the highway at a distance of five hundred (500) feet ahead. Lighted lamps shall also be required any time the weather conditions require usage of the motor vehicle's windshield wipers to operate the vehicle in a careful and prudent manner as defined in Section 304.012, RSMo. The provisions of this Section shall be interpreted to require lighted lamps during periods of fog even if usage of the windshield wipers is not necessary to operate the vehicle in a careful and prudent manner.

When Lights Required — Violation — Penalty.
1. 
No person shall drive, move, park or be in custody of any vehicle or combination of vehicles on any street or highway during the times when lighted lamps are required unless such vehicle or combination of vehicles displays lighted lamps and illuminating devices as hereinafter in this Article required. No person shall use on any vehicle any approved electric lamp or similar device unless the light source of such lamp or device complies with the conditions of approval as to focus and rated candlepower.
2. 
Notwithstanding the provisions of Section 307.120, RSMo., or any other provision of law, violation of this Section shall be deemed an ordinance violation and any person who violates this Section as it relates to violations of the usage of lighted lamps required due to weather conditions or fog shall only be fined ten dollars ($10.00) and no court costs shall be assessed.
For purposes of this Article, a lamp, light, or other piece of lighting equipment consisting of multiple light-emitting diodes shall be deemed to be operating properly so long as not less than seventy-five percent (75%) of the light-emitting diodes are operating properly.
Except as in this Article provided, every motor vehicle other than a motor-drawn vehicle and other than a motorcycle shall be equipped with at least two (2) approved headlamps mounted at the same level with at least one (1) on each side of the front of the vehicle. Every motorcycle shall be equipped with at least one (1) and not more than two (2) approved headlamps. Every motorcycle equipped with a sidecar or other attachment shall be equipped with a lamp on the outside limit of such attachment capable of displaying a white light to the front.
A. 
Except as hereinafter provided, the headlamps or the auxiliary driving lamp or the auxiliary passing lamp or combination thereof on motor vehicles other than motorcycles or motor-driven cycles 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 as to reveal persons and vehicles at a distance of at least three hundred fifty (350) 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 (100) 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.
Every person driving a motor vehicle equipped with multiple-beam road lighting equipment, during the times when lighted lamps are required, shall use a distribution of light, or composite beam, directed high enough and of sufficient intensity to reveal persons and vehicles at a safe distance in advance of the vehicle, subject to the following requirements and limitations: Whenever the driver of a vehicle approaches an oncoming vehicle within five hundred (500) feet or is within three hundred (300) feet to the rear of another vehicle traveling in the same direction, the driver shall use a distribution of light, or composite beam, so aimed that the glaring rays are not projected into the eyes of the other driver, and 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.
A. 
Every motor vehicle and every motor-drawn vehicle shall be equipped with at least two (2) rear lamps, not less than fifteen (15) inches or more than seventy-two (72) inches above the ground upon which the vehicle stands, which when lighted will exhibit a red light plainly visible from a distance of five hundred (500) feet to the rear. Either such rear lamp or a separate lamp shall be so constructed and placed as to illuminate with a white light the rear registration marker and render it clearly legible from a distance of fifty (50) feet to the rear. When the rear registration marker is illuminated by an electric lamp other than the required rear lamps, all such lamps shall be turned on or off only by the same control switch at all times.
B. 
Every motorcycle registered in this State, when operated on a highway, shall also carry at the rear, either as part of the rear lamp or separately, at least one (1) approved red reflector which shall be of such size and characteristics and so maintained as to be visible during the times when lighted lamps are required from all distances within three hundred (300) feet to fifty (50) feet from such vehicle when directly in front of a motor vehicle displaying lawful undimmed headlamps. A motorcycle may be equipped with a means of varying the brightness of the vehicle's brake light for a duration of not more than five (5) seconds upon application of the vehicle's brakes.

Every such reflector shall meet the requirements of this Article and shall be mounted upon the vehicle at a height not to exceed sixty (60) inches nor less than fifteen (15) inches above the surface upon which the vehicle stands.
D. 
Any person who knowingly operates a motor vehicle without the lamps required in this Section in operable condition is guilty of an ordinance violation.

When such device shall consist of reflecting buttons, there shall be no fewer than seven (7) of such buttons covering an area equal to a circle with a three-inch diameter. The total subtended effective angle of reflection of every such device shall be no less than sixty degrees (60°) and the spread and efficiency of the reflected light shall be sufficient for the reflected light to be visible to the driver of any motor vehicle approaching such animal-drawn vehicle from the rear of a distance of not less than five hundred (500) feet.
