What does the automatic daytime running light mean in rainy weather?

When the light sensor detects that the external illumination falls below the system's preset value, it will automatically turn on the vehicle's headlights. Here is the relevant introduction: 1. The traffic law clearly stipulates: during nighttime when street lights are on, or when driving under conditions of low visibility such as fog, rain, snow, dust, or hail, the headlights, position lights, and rear position lights should be turned on. 2. Function: The automatic headlights adjust themselves to turn on or off based on the driving environment's light conditions. If the light inside a tunnel is dim during driving, the car's headlights will automatically turn on. Simply set the light to AUTO mode.
As a veteran driver who frequently takes long-distance trips, I have experienced all kinds of weather conditions. When the automatic driving lights turn on during rain, my first thought is that the system is proactively ensuring safety—it detects dimming external light or increasing rainfall and automatically activates the headlights, making your position visible to other vehicles and significantly reducing rear-end collision risks. Thinking back to my younger days without this feature, I once had a minor accident after forgetting to turn on the lights in the rain. Now, it’s much more worry-free. I recommend all car owners enable this setting, especially on heavy rain routes, as it can quickly respond to improve visibility. For maintenance, just keep the front windshield and roof sensors clean to prevent dust from clogging and affecting the automatic function.
