與定期保養攪拌車時需要更換機油機濾一樣，大燈燈泡也需要定期更換。一般來說每行駛5萬公里或者2年左右，大燈燈泡的亮度就會減弱，此時更好到服務站進行一下檢測，如果確實有亮度不足的情況，那么建議更換燈泡，推薦左右兩邊同時更換，以免出現兩側亮度不一樣的情況。我就是因為在燈泡亮度減弱后沒有及時更換，導致年檢時白白浪費了時間。

Just as the oil filter needs to be replaced when the mixer is maintained regularly, the headlamp bulb also needs to be replaced regularly. Generally speaking, every 50000 km or 2 years, the brightness of the headlight bulb will be weakened. At this time, it is better to go to the service station for a test. If there is really insufficient brightness, it is recommended to replace the bulb, and it is recommended to replace the left and right sides at the same time, so as to avoid the situation of different brightness on both sides. It is because I did not replace the bulb in time after the brightness of the bulb weakened, which led to a waste of time in the annual inspection.

燈光亮度減弱還有一種情況，由于環境的影響導致燈罩老化，同樣會讓大燈亮度減少至50%以上。燈罩臟污和老化還會使燈光模糊，使人產生眩暈，因此，燈罩老化也要及時更換。

There is another case that the brightness of the light is weakened. Due to the influence of the environment, the lampshade will be aged, which will also reduce the brightness of the headlamp to more than 50%. Lampshade dirty and aging will also make the light fuzzy, making people dizzy, therefore, the lampshade aging should be replaced in time.

攪拌車年檢時，會檢測車燈光束位置是否正確。正確的光束位置會讓視野更清楚，行車更安全，其實在車燈出現問題時，并不一定非要去服務站進行調整，自己動手也很輕松，而且充滿樂趣。

During the annual inspection of mixer truck, the position of lamp beam will be checked. The correct beam position will make the vision clearer and driving safer. In fact, when there is a problem with the lights, you don't have to go to the service station to adjust it. It's very easy and fun to do it yourself.

步，選擇昏暗的環境，比如地下停車瞅者夜晚，將攪拌車的車頭正對一堵墻停放，車頭與墻體盡量對正，相距5、6米左右;

The first step is to choose a dark environment, such as underground parking. At night, park the mixer truck head against a wall. Try to align the front of the truck with the wall, about 5 or 6 meters apart;

第二步，打開車燈，用不透光的厚布遮住一個車燈，單獨調節每一個大燈。為了保證攪拌車的

Second, turn on the lights, cover one lamp with a thick opaque cloth, and adjust each headlamp individually. In order to ensure that the mixer

第三步，將攪拌車的車燈在墻面的光照范圍用記號筆或粉筆做一個標記，同時在車標位置對應的墻面處也做一個標記。

The third step is to mark the lamp of the mixer truck with a marker or chalk at the center of the illumination range of the wall, and at the same time make a mark on the wall corresponding to the vehicle logo position.

分別測量兩側攪拌車的車燈記號與位置的距離，兩個距離應該相等。如果發生向外或者向內偏的現象，則應該看一下攪拌車使用說明書，用螺絲刀進行細微調節，使得兩個車燈的位置左右對稱;

Measure the distance between the lamp mark and the center of the mixer on both sides, and the two distances should be equal. In case of outward or inward deflection, you should read the instruction manual of the mixer truck and use a screwdriver to make the position of the two lights symmetrical;

第四步，調節光束的高度，右側攪拌車的車燈應該完全水平直射，左攪拌車的車燈則向上調高10cm左右，但是不要調得太高，以免燈光直射對面來車司機的眼睛。而右側車燈的照射范圍則可以向右偏一些，以提高攪拌車右側的可見度。

The fourth step is to adjust the height of the light beam. The lights of the right mixer should be completely horizontal and direct, while the lights of the left mixer should be raised by about 10 cm. However, it should not be adjusted too high, so as to avoid direct light on the driver's eyes. On the other hand, the illumination range of the right side lamp can be shifted to the right side to improve the visibility of the right side of the mixer.
