Upgrading from halogen to xenon would be a bit of a hassle. In addition to replacing the bulbs, electronic controls would have to be drilled into the car to raise voltage (called stabilizers in the jargon). In addition, xenon bulb generates arc light between two electrodes because xenon gas is stimulated by 23,000 v high voltage current. Because arc light tends to drift, xenon lamps must be lensed to focus well. If there is no lens, on the one hand, the brightness will rise too high, and on the other hand, the unstable light shape will lead to direct light to the eyes of the driver of the opposite vehicle, which will lead to the phenomenon of far-light dog. So the industry has no lens upgrade xenon lamps is a rogue story.
　　Obviously, upgrading from halogen lamps to xenon lamps is not a good choice. As mentioned at the beginning of this article, why did LED headlights not become popular?
　　Because LED headlights on the market today, despite the advantages mentioned at the beginning of this article, are not as unstable as xenon bulbs, and do not need to be equipped with stabilizers in the car. But there is a fatal problem: two-sided lighting designs, rather than full-body lights like halogen and xenon lamps, cause the light to look bad and look bright, but when you actually get in the car, you don't see it coming very far. Upgrade to such LED headlights, not only is not safe, but also increased security risks!
