How to adjust Volkswagen low beam headlights
Low-beam headlights are an important lighting tool when driving at night. Correctly adjusting low-beam headlights can not only improve driving safety, but also avoid dazzling drivers of oncoming vehicles. Recently, the topic of vehicle lighting adjustment has sparked heated discussions on major automotive forums and social platforms. This article will introduce in detail the adjustment method of low beam headlights of Volkswagen models, and attach structured data for reference.
1. The necessity of low beam adjustment
The adjustment of low beam headlights directly affects night driving safety. If the light is too high, it will shine into the eyes of the driver of the oncoming vehicle, causing dazzling; if the light is too low, it will not provide sufficient lighting distance. According to traffic regulations, the irradiation range of low beam lights should be between 30 meters and 50 meters in front of the vehicle.
