速腾后雾灯为什么一个亮一个不亮

因为该车系只安装了一个后雾灯，因此一个亮一个不亮。根据我国的相关规定，为了区分刹车灯与后雾灯，所以在安装后雾灯的时候只安装左侧，右侧不进行安装后雾灯；因此，一旦发现车辆的后雾灯发生故障，建议立即维修，以免无法正常使用造成更大的伤害。

车辆后雾灯最主要的作用就是当车辆驾驶在雾、雪、雨或者是能见度很低的环境中时，为了方便后方来车以及行人发现而安装在车辆尾部，因此，即使是不同品牌的不同车系的后雾灯颜色几乎都是一样的，皆采用红色，且发光强度比尾灯要大得多。

后雾灯只有一个亮的原因是：后雾灯只有一边，另一边是属于倒车灯。雾灯是雨雾天气里使用的灯光信号，其主要特点是雾中穿透性强，在能见度低下的天气里容易让车辆或行人及早注意到，从而有效预防事故的发生，其作用是在雨雾天气行车时照明道路，提高驾驶员与周围交通参与者的能见度，使来车和行人在较远处发现对方。雾灯使用的注意事项是：能见度低于100米后必须要开启雾灯并注意降低车速；能见度低于30米需要打开雾灯靠边停车并开启危险警告灯；对于雨雾雪或尘埃弥漫天气开启雾灯和降低车速不能开启双闪。
