Bulbs are often damaged. Bulbs are often damaged in small lamps. After bulbs are replaced for a period of time, the filament is blown or directly "choked" after the lamp is turned on. This situation is more common. Most of the reasons are that the filament is blown because the instantaneous output voltage is too high. In this case, we should pay special attention to the bearing range of the fuse, use the fuse correctly, and do not use the fuse with higher rating, If you should use 10a, don't use 15A.

2.前照燈光暗淡前照燈暗淡也分情況，有些老舊的鹵素燈可能會存在這種情況，這跟燈泡本身有關系。還有一種就是由于小故障導致，如燈光保險絲松動、燈光接頭不實、前照燈開關或繼電器接觸不好、汽車線路存在漏電導致電壓降過大或者負荷過大接地不好等，所以當燈光出現此類情況時，就可以根據上述順藤摸瓜一一檢查。

2. The headlamp is dim. The headlamp is dim, which may exist in some old halogen lamps. It has something to do with the bulb itself. The other is caused by small faults, such as loose light fuse, false light connector, poor contact of headlamp switch or relay, excessive voltage drop caused by electric leakage of vehicle circuit or excessive load, poor grounding, etc. so when the light appears this kind of situation, you can check one by one according to the above.

3.一側前照燈亮度正常、另一側暗淡這種情況也時常遇見，大部分情況都是大燈本身的問題，很多車主因為維修價 格的原因很少維修。另一種情況就是前照燈燈光暗淡的一側存在搭鐵不好或者插頭處接觸不實的情況。

3. One side of the headlamp brightness is normal and the other side is dim. Most of the problems are caused by the headlamp itself. Many car owners seldom repair it because of the maintenance price. Another situation is the poor grounding or false contact at the plug on the dim side of the headlamp.

4.遠光或近光燈不亮車頭大燈不亮的情況不多，導致原因也比較簡單，一般多是導線斷路或插頭接觸不好、遠光或近光燈保險絲熔斷、燈光繼電器損壞、燈泡損壞或大燈總成損害。

4. The high beam or low beam does not work, and the front headlight does not work. The causes are relatively simple. Generally, the wires are open or the plug is not well contacted, the high beam or low beam fuse is blown, the light relay is damaged, the bulb is damaged or the headlamp assembly is damaged.

5.小燈不亮小燈不亮的情況很常見，可以說很多車上都存在，只是車主并不在意。小燈不亮一般多是燈泡損壞憋了，之后就是保險絲熔斷，其次是電路故障，至于繼電器也有影響，但影響的是一條線路，也就包括小燈。

5. It's very common that the small light doesn't work. It can be said that many cars have it, but the owners don't care. When a small lamp doesn't work, it is usually because the bulb is damaged and suffocated, and then the fuse is blown, followed by the circuit failure. As for the relay, it also affects a circuit, including the small lamp.

6.剎車燈不亮剎車燈不亮的原因基本跟小燈不亮原因差不多，但需要注意的一點是，剎車燈還多了一個控制開關——剎車開關，當踩剎車時開關接通點亮剎車燈（大部分車型）。

6. The reason why the brake light doesn't work is almost the same as the reason why the small light doesn't work, but it should be noted that the brake light also has a control switch - the brake switch. When you step on the brake, the switch will turn on and turn on the brake light (most models).

7.所有燈光都不亮說了這么多關于個別汽車燈光的問題，那么萬一全車的燈光都不亮怎么辦？那你可以大膽猜測，一定是這車“進水”了。其實全車燈光都不亮的情況，在正常用車中很難碰到，除了汽車電源被斷開之外（包括汽車電源管理熔斷器熔斷）或者蓄電池極

7. All the lights don't work. I've talked so much about the lights of individual cars. What if the lights of the whole car don't work? Then you can make a bold guess that the car must be "flooded". In fact, it is very difficult to encounter the situation that the lights of the whole car are not on, except that the power supply of the car is disconnected (including the fusing of the power management fuse) or the battery pole

度虧電以致損壞，這些情況都比較端正常用車不會碰到。

It is normal that the car will not be damaged due to power loss.
