What lights should be turned on under good lighting conditions?

When driving at night on roads with good lighting conditions, low beam headlights should be used. Poor lighting conditions mean that distant and nearby sections of the road are not visible, in which case high beam headlights should be turned on to see farther and more clearly. Conversely, under good lighting conditions, meaning both distant and nearby areas are clearly visible, it is safest to use low beam headlights. Below is relevant information about low beam headlights: 1. Definition: Low beam headlights have an illumination range of approximately 30-40 meters. Experiments show that when driving at 55 km/h at night, the braking distance upon immediately noticing a situation is exactly 30 meters. 2. Function: The area in front of the beam cutoff line is brightly lit, allowing clear distinction of objects, with a clearly visible illuminated area of 2-3 meters in diameter on the ground. The area from the beam cutoff line to about 30-40 meters mainly relies on ground-reflected light, where brightly colored objects can be distinguished, but stationary dark-toned objects on the road are harder to detect.
When driving in ample lighting conditions, such as during clear daylight or well-lit urban areas with good street lighting, I usually just turn on the low beams. This is because low beams make it easier for other drivers to notice my vehicle, enhancing road safety. While daytime running lights are effective during the day, they can sometimes be insufficiently bright or overlooked. On highways or in foggy conditions, even if the lighting is good, I make it a habit to turn on the lights as a precaution. Additionally, many new cars come with automatic lighting systems that activate the low beams upon starting, which is both convenient and professional. Developing this habit can help reduce accidents—remember to regularly check for oxidation in the lamp sockets or aging wiring to avoid malfunctions and potential issues.
I'm well-versed in automotive lighting systems. Under good lighting conditions, I prioritize using daytime running lights (DRLs) or low beams. DRLs are specifically designed for daytime use, featuring low power consumption and long lifespan, significantly improving vehicle visibility in reflective or shaded areas. Low beams are suitable for broader scenarios, including dusk and complex road conditions. Modern vehicles often come with automatic adjustment functions, so I recommend checking if these settings are enabled—for instance, ensuring proper sensor sensitivity. During long-term use, pay attention to fuse and wiring conditions—battery power issues may also affect lighting response. Timely maintenance can extend component lifespan.
