When common sense fails... remember its the law:
Wisconsin State law requires drivers to use headlights as follows:
Wis. Stat. § 347.06(1), requires that all required headlamps, tail lamps, and clearance lamps be lighted when operating a vehicle during “hours of darkness” or a “period of limited visibility.”
§ 340.01(23): Defines “hours of darkness” as the period from 30 minutes after sunset to 30 minutes before sunrise.
§340.01 (43d) "Period of limited visibility" means any time that weather conditions limit visibility such that objects on a highway are not clearly discernible at 500 feet from the front of a vehicle.
In other words, turn your lights on in heavy rain, snow and fog when you cannot see 500 feet (less than two (2) football fields or about five (5) basketball courts) in front of your vehicle.
Headlights activation is just as important for other vehicles TO SEE YOU as to see the roadway yourself. and don't trust your "Automatic lights" to do the job for you. 😁
