Want to replace halogen lamps, why is it better to replace LED lamps than xenon lamps?

The actual efficiency of common car luminous bodies is 3 times that of xenon lamps and 5 times that of halogen lamps.
In addition, many LED bulbs for cars on the market are already designed "original car original position", which is more convenient to modify.
However, the installation of xenon lamps is not simple. You need to install additional ballasts to disperse the working current and voltage.
When the headlight switch is turned on, the ballast instantly boosts the 12V voltage of the car battery to about 23000V. After the gas discharges and emits light, it maintains an AC voltage of 85V and the working current is 400A. When 23000V leaks, the consequences are disastrous.

Some later modified xenon lamps have uneven ballast quality. If there are some faults or problems with high voltage and high current, it may be easier to burn out the car's fuse.
Once these faults occur, it is very troublesome to check and find the cause. In comparison, LED lamps will be more worry-free.
Finally, LED lamps light up immediately after being turned on, with relatively low delay.
Automotive LED lights do not require hot start time and can light up in a few microseconds; traditional halogen bulbs have a delay of about 0.3s.
Xenon lamps, due to the instantaneous boost discharge process of the ballast, usually reach 25% of the final brightness after 1s, and 80% of the final brightness after 4s.
The longer the bulb is used, the brighter it is. After 2-4 minutes, the brightness tends to stabilize.
If you use xenon lamps to modify headlights that do not have integrated high and low beams, there is no way to flash the high beam to remind other vehicles, which affects safety.
