我很高兴现在回答您的问题卤素大灯与氙气。

At the first, I think halogen headlights and xenon are all good in different possitions.

Xenon will be brighter than halogen headlights.

Meanwhile, the life time of Xenon is also longer than halogen headlights.

But most of halogen headlights are all small size, so they are plug and play.

最重要的是卤素大灯比氙气便宜得多。

而且在雾天，所有卤素大灯的穿透力都比氙气强。

再次感谢您关于卤素大灯与氙气的问题！
