What lights should be turned on in rainy weather?

In rainy conditions, you should turn on the headlights or fog lights. When the rain is heavy, the rainwater itself can obstruct visibility, and water on the road surface can be kicked up by the tires of the vehicle ahead, creating a mist that also significantly affects visibility. In such cases, turning on the headlights or fog lights can improve visibility. In fact, traffic regulations have specific rules regarding light usage in rainy weather: "During periods when streetlights are on at night, or when driving in conditions of low visibility such as fog, rain, snow, sandstorms, or hail, headlights, position lights, and rear lights must be turned on." Therefore, the most important aspect of driving in the rain is ensuring that other vehicles can always see you. Even if the rain is so heavy that the outline of the vehicle is unclear, the lights can still indicate the presence of a vehicle in that position, which is safer for both yourself and others. 1. Position lights (or daytime running lights): In light rain or when the rain first starts, position lights can be effective. However, if the rain becomes heavier, the illumination intensity of ordinary halogen position lights may not be sufficient. Nowadays, some models that use LED daytime running lights instead of position lights (such as the Audi A3 in the image below) have better illumination intensity and can handle heavier rain. 2. Headlights: When the rain reaches a moderate level, it is necessary to turn on the low beams, and you can also turn on the front fog lights at the same time. These two are collectively referred to as headlights. At this point, the main purpose of the headlights is not for illumination but to increase your own visibility. For example, in the image below, the vehicle in the rearview mirror has turned on the low beams and front fog lights, making it particularly noticeable in the rearview mirror.
