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.前照灯光暗淡前照灯暗淡也分情况，有些老旧的卤素灯可能会存在这种情况，这跟灯泡本身有关系。还有一种就是由于小故障导致，如灯光保险丝松动、灯光接头不实、前照灯开关或继电器接触不好、汽车线路存在漏电导致电压降过大或者负荷过大接地不好等，所以当灯光出现此类情况时，就可以根据上述顺藤摸瓜一一检查。

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.

3.一侧前照灯亮度正常、另一侧暗淡这种情况也时常遇见，大部分情况都是大灯本身的问题，很多车主因为维修价 格的原因很少维修。另一种情况就是前照灯灯光暗淡的一侧存在搭铁不好或者插头处接触不实的情况。

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.远光或近光灯不亮车头大灯不亮的情况不多，导致原因也比较简单，一般多是导线断路或插头接触不好、远光或近光灯保险丝熔断、灯光继电器损坏、灯泡损坏或大灯总成损害。

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.小灯不亮小灯不亮的情况很常见，可以说很多车上都存在，只是车主并不在意。小灯不亮一般多是灯泡损坏憋了，之后就是保险丝熔断，其次是电路故障，于继电器也有影响，但影响的是一条线路，也就包括小灯。

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.刹车灯不亮刹车灯不亮的原因基本跟小灯不亮原因差不多，但需要注意的一点是，刹车灯还多了一个控制开关——刹车开关，当踩刹车时开关接通点亮刹车灯（大部分车型）。

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.所有灯光都不亮说了这么多关于个别汽车灯光的问题，那么万一全车的灯光都不亮怎么办？那你可以大胆猜测，一定是这车“进水”了。其实全车灯光都不亮的情况，在正常用车中很难碰到，除了汽车电源被断开之外（包括汽车电源管理熔断器熔断）或者蓄电池极

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

度亏电以致损坏，这些情况都比较端正常用车不会碰到。

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