尾灯夜间不亮

[lindarong]

我的车尾灯夜间不亮. 两个都不亮, 刹车时是亮的, 应该不是灯泡问题; 车前大灯夜间会亮, 应该不是传感器问题. 诸位有何高见?

应该是灯泡问题。留意一下，尾灯灯泡是两个灯丝，其中一根断了。找个新灯泡，换上去，试一下就知道了。

there are 3 bulbs at the back, and 3 int the front ... make sure all of them work

then check the harness, maybe it is short somewhere (continuity test)

看来楼主的汽车没有问题，问过就不再来看了。

As ccc pointed out, break light bulb has 2 filaments. 1 for normal brightness, and another 1 for extra brightness when braking.

One of the filament burned, which cause it does not light up during normal operation. The second filament still not burned yet, therefore you still see light when you braking.

The normal filament is the one that has shorter life span because it is on whenever you turn on your light. Therefore, it is common that is burn first.

Please replace the bulb. It is illegal to operate a car with burn light bulb
