What lights should be used when driving at night under poor lighting conditions without street lights?

When driving at night without street lights and under poor lighting conditions, high beams should be turned on. Here is some relevant information: Car lights: Car lights refer to the lamps on the vehicle, which are tools for road illumination during nighttime driving and also serve as signaling devices for various vehicle movements. Car lights are generally divided into headlights, taillights, turn signals, etc. Halogen headlights: Halogen lamps are actually a special type of incandescent lamp. Their principle is that when current passes through a resistor, it generates heat, and when the temperature is high enough, it emits blackbody radiation with wavelengths in the visible light spectrum. There are generally two types of halogen lamps: iodine tungsten lamps and bromine tungsten lamps, which operate on the same principle. When an incandescent lamp is lit, although the filament temperature does not exceed the melting and boiling points of tungsten, a small amount of tungsten still volatilizes at high temperatures. When the volatilized tungsten atoms encounter the cooler bulb shell, they condense and precipitate. Over time, a layer of blackened tungsten film accumulates on the bulb shell.
I've been driving at night for nearly 20 years and pay special attention to safe driving on roads without streetlights. In such poorly lit conditions, you must use high beams—they illuminate over 100 meters ahead, helping you spot potential hazards like sudden pedestrians or obstacles earlier. Driving with low beams on highways or rural roads severely limits visibility and increases accident risks. But remember: switch back to low beams immediately when encountering oncoming traffic or spotting other vehicles' lights to avoid blinding others—a rule emphasized repeatedly in driving tests and traffic laws. At car club meetups, I've shared this advice: neglecting to switch can annoy others at best or trigger chain-reaction crashes at worst. Make it a habit to check your lighting system before starting to prevent mid-drive failures. Proper light usage ensures a safe and stress-free nighttime journey.
Last time when driving home from camping in the forest at night, the entire road was pitch black without streetlights. I immediately turned on the high beams, and the view became bright, allowing me to clearly see distant curves and large trees, as if night vision mode was activated. Suddenly, a wild rabbit jumped out, but thanks to the early detection from the lights, I managed to avoid it. When encountering oncoming vehicles, I casually switched to low beams, ensuring safety for everyone. Actually, many people don't understand how to use lights under unlit conditions and only complain about nighttime driving stress on forums. My suggestion: use high beams on dark sections and switch back to low beams when vehicles approach. It's a simple yet crucial operation. As a car enthusiast, I often post short videos demonstrating light switching to avoid laziness causing risks.
After studying automotive lighting systems, I've found that using high beams is most reasonable when driving at night without streetlights. Their intense beam and long range enhance visibility and reduce blind spots. Compared to low beams that illuminate nearby areas, high beams allow drivers to react to potential threats several seconds earlier. Modern vehicles come with automatic switching functions, but manual operation is more reliable: use high beams to ensure good visibility, then switch back to low beams when approaching other vehicles to prevent glare. This topic is frequently discussed in Xiaohongshu's car communities, as incorrect light usage can lead to accident disputes.
