What is the Difference Between Low Beam and High Beam Headlights?
1 Answers
The difference between low beam and high beam headlights lies in the adjustment of light intensity based on the distance of the filament: 1. The high beam is at its focal point, emitting light that is parallel and highly concentrated, providing greater brightness and the ability to illuminate distant and high objects; 2. The low beam is beyond its focal point (between 1 and 2 times the focal distance), emitting light in a divergent state, which can illuminate a larger area of nearby objects. Here is some relevant information: 1. When driving in dark areas without streetlights, or during dusk when it is darker or at dawn when light is just appearing, you must turn on the low beam headlights; if you encounter fog, snow, or heavy rain, which obstructs visibility, you must also turn on the low beam headlights even during the day; 2. On some roads where there is lighting but the brightness is insufficient, you should also use the low beam headlights. Under normal circumstances, when driving on urban roads, you should use the low beam headlights because urban areas generally have good lighting conditions. Using high beams can easily dazzle oncoming vehicles and cause accidents. On highways or in rural areas without streetlights, you can use high beams to expand your field of vision.
