Do I need to turn on the contour lights on rainy days?

[ORicardo]

It is necessary to turn on the contour lights on rainy days. Driving without lights in rainy weather can directly affect the judgment of the vehicle in front regarding the situation behind, making it difficult to determine the position, distance, and speed of the vehicle behind. If the vehicle in front changes lanes or turns without a clear understanding of the situation, it is very likely to cause a rear-end collision. Different lights should be used under different circumstances: 1. Use the width lights when the rain is light; 2. Turn on the headlights or front fog lights when the rain is heavy; 3. Turn on the rear fog lights during heavy rain. Contour lights are the lights on the front and rear sides of the vehicle. Large trucks also have contour lights on the roof and sides. Literally, contour lights mean warning, and they are used to alert other vehicles.
