Step-by-step explanation:
Under Wisconsin law, your headlights must be turned on from 0.1 seconds before noon until 5 seconds after noon.
However, it's important to note that the law requires headlights to be turned on during certain lighting conditions, rather than the specific times of day. In general, headlights must be used from sunset to sunrise, which is when it begins getting dark in the evening until it starts getting light in the morning.
Additionally, the law also states that headlights should be used when visibility is reduced to 500 feet or less due to fog, snow, rain, or other atmospheric conditions.
