You can see the effect of normal headlights about 5~ 10 meters in front of the road. The exposure distance of car headlights has been adjusted at the factory. If the headlamp itself has never moved, it will never need to be adjusted. Generally speaking, after replacing the headlight assembly, the front of the vehicle is rebuilt after the accident, and even after replacing the light bulb, the height of the lamp may change. If the headlight or light bulb has moved, it is necessary to check whether the light bulb or headlight is installed in place before adjusting it.

Lighting introduction

There are usually several situations where the lights on both sides are getting closer or farther away; The irradiation distance of headlights on both sides is different, with one side high and one side low; Headlights on one side are biased.

The low beam irradiation distance of most headlights is about 30-40m, and the high beam irradiation distance is about 100m. If the lighting distance is too close, the distance you can see when driving at night is also close, which is not conducive to driving safety. If the lighting distance is too far, due to the limited lighting intensity, the whole road ahead will not be bright, and the low objects and potholes on the ground will not be seen, which is not conducive to driving safety.
