Here are the applicable situations for high and low beam lights: 1. High beam: (1) At night when there are no street lights or poor lighting: High beam lights are generally suitable for driving at night on roads without street lights or with poor lighting, such as on poorly lit national highways or freeways. (2) When the vehicle speed is above 30 km/h: When the vehicle speed is above 30 km/h, high beam lights can be used to illuminate up to 150 meters ahead, ensuring driving safety. 2. Low beam: (1) When an oncoming vehicle is within 150 meters: When an oncoming vehicle is within 150 meters, switch to low beam to avoid obstructing the vision of the oncoming driver. (2) When the vehicle speed is below 30 km/h: If the vehicle speed is below 30 km/h, low beam lights should be used.

I usually drive to and from work, and the use of high and low beams is quite particular. On city streets, where there are streetlights, I mainly use low beams to avoid dazzling pedestrians or other drivers, especially in busy commercial areas. When I leave the city and drive on rural roads, where it's dark and less crowded, I switch to high beams for better visibility. However, I immediately switch back to low beams when encountering oncoming traffic to avoid causing danger. In rainy or foggy weather, high beams can reflect light and reduce visibility, so I stick to low beams and use fog lights as an aid. When driving on highways at night, I use high beams on open lanes for a broader view but turn them off in advance when overtaking or approaching toll booths. Safety awareness is key, especially for new drivers who need to practice switching beams to develop good habits—otherwise, fines and accidents can become major issues.

When driving with my family, I am more cautious about the choice between high and low beams, as safety is the top priority. On dark suburban roads, I use high beams to see distant obstacles clearly, but immediately switch to low beams when encountering pedestrians or oncoming vehicles to protect others and avoid accidents caused by glaring lights. In urban environments, even when lighting is insufficient, I only use low beams and control speed to reduce risks. During rainy or foggy weather, low beams are the right choice, as high beams can worsen road reflections. I also teach my children to observe the timing of light switches while riding, such as lowering our own lights when the lights from oncoming vehicles are glaring. Regularly checking the condition of the lights prevents malfunctions and ensures safety in critical moments. The rules for nighttime driving are clear—don't take shortcuts by misusing high beams.

As a commuter who frequently drives at night, I switch my car lights daily after work on dark roads. On open highways, I use high beams for better visibility and time efficiency; but when approaching vehicles or pedestrian areas, I switch to low beams to avoid causing glare. In the city, I only use low beams to adapt to street lighting. During rainy or foggy weather, I switch more frequently, sticking to low beams for safety. Conserving energy is the key.
