Car headlights are low beam but high beam is not bright. What is the reason?
There is a light bulb in the headlight, but there are two filaments, one is the high beam and the other is the low beam. If the low beam is not bright and the far beam is bright, then the low beam filament is broken. We have to change the light bulb. Then the cost is very cheap. In addition, if the low beam lights of the two lamps are not on at the same time, it may be that there is something wrong with your low beam controller, or the contact is oxidized, which leads to poor contact and needs to be repaired in time.
Extended data
Use of low beam and high beam
1. Generally, it is best not to turn on the high beam when driving in urban areas, because the lighting conditions in urban areas are generally better. The high beam angle is too high, which easily shakes the glasses of the opposite car and the surrounding pedestrians, affecting the line of sight, which is an unsafe and impolite driving behavior.
2. However, turning on and off the high beam alternately at night can replace the horn to remind pedestrians and vehicles around without causing too much noise.
3. Driving in high-speed and suburban areas without street lights can turn on the high beam and broaden your horizons. However, when there is a car across the street that needs to meet, for the sake of safety and courtesy, switch to low beam.
