What lights should be used for night driving on highways?

[SanAmy]

When driving on highways at night, high beams should be used because highway street lights are generally not very dense, making it difficult to clearly see the road conditions. Additionally, low beams only illuminate up to 30 meters, and vehicles on highways travel at high speeds. If there is an obstacle ahead, the driver would have very little time to react at such a short distance, which could easily lead to an accident. Here are some related points: 1. High beam distance: High beams provide visibility up to about 100 meters, giving drivers more reaction time in case of sudden situations. However, keeping high beams on continuously is not advisable. If the distance to the vehicle ahead is less than 100 meters, it's best to switch from high beams to low beams. 2. No need for high beams in tunnels: There are many tunnels on highways, and there is no need to use high beams when passing through them as the lighting inside tunnels is very bright.
