What does it mean when the DRL light is on?

DRL stands for Daytime Running Light, which is a mode of the headlights. Here are the specific details about daytime running lights: 1. Purpose: The daytime running lights are not for the driver to see the road clearly but to alert other vehicles. For example, in foggy or snowy conditions, white vehicles can be easily misidentified, so it is necessary to turn on the lights in such situations. 2. Function: From the perspective of the surrounding environment, dedicated daytime running lights can improve visibility, making vehicles more noticeable. Compared to existing lighting devices, this technology, specifically designed for daytime use, is more direct and effective. If the driver turns on the regular headlights in the dark, the daytime running lights will automatically turn off, which plays a significant role in driving safety configurations.
