I am pleasure to answer your question halogen headlights vs xenon now.

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.

The most important is halogen headlights are much cheaper than xenon.

And also all halogen headlights have a stronger penetrating than xenon during foggy days.

Thank you for your question about halogen headlights vs xenon again!
