其实从各大厂商推出的新车就可以看出，卤素灯=低配，氙气灯=中配，LED=高配，那么，
卤素灯就真的那么不好么?气灯和LED到底强在哪?
卤素大灯是新一代白炽灯，充有溴碘等卤族元素或卤化物的钨灯。
通电后，电能把钨丝加热到白炽状态进行发光，电能转化为热能，再转化为光能。
优点:
1、成本低、制作简单。
2.色温较低，穿诱性好。
3、开启速度快。
4、遇到雨雾天气时，配合反光罩穿透性更好、
劣缺点:
温度高、耐用性差、亮度低。
氙气灯车灯优缺点
氙气灯灯(HID)的工作原理是高压气体放电灯，
将12V电压增压到23000V的超高电压，激穿填充在石英管的气气使它发光，
然后再将电压转成85V左右，稳定持续供应氙气灯泡发光。
优点
1.亮度高:一般为卤素灯的3倍
2色温高: HID灯可以制造出4000-12000k的色温光，接近正午日光的颜色，人眼的接受度及舒适度最高。
3.寿命长:一组 HID 气体放电灯大约为3000小时
4.耗电少: HID的功率一般只有35 W，而普通车灯的功率一般为55W.
5、显档次，一般只会配备在中高端车型中，在夜间提高身份与面子的象征.缺点
缺点
1、发热高，会达到300-400度，灯置容易被烤
2、会有延迟
LED灯车灯优缺点
LED是Light Emitting Diode的缩写，中文名字是一一发光二极管，PN结。
它们如今常常以灯箱、招牌及各种电器的指示灯和背光灯的角色出现，也往往是汽车尾灯、高位刹车灯、日间行车灯的重要组成。而ED大灯就是利用LED作为光源制造出的照明器具。
优点：
1、使用寿命长:目前用在汽车上的LED元件基本都能至少达到50000小时。
2、耐用性好，不易破碎抗冲击性和抗震性能好。
3、响应速度快。
4、亮度高。
缺点：
虽然一直在下降，但是LED的成本依然较高，所以一般只会出现在中高配车型中
卤素灯、氙气灯、LED灯实用情况分析：
卤素灯：穿透力强，500小时寿命，
氙气灯：现在的主流，亮度好，不能么稳定，现在技术成熟了，稳定度，好很多，但是改装通常要破坏车体，寿命3000小时，冷光，雨雾天穿透力弱;
LED灯：节能，够亮，寿命长，一般都可以达到5000小时，技术稳定，无损安装.从性价比各方面来说led灯是最实用的。
卤素灯:在光线黑暗的情况下，偏黄的卤素灯亮起来没那么显眼，最大输出1200流明，相当于1200跟蜡烛
氙气灯:输出4500流明，相当于4500根蜡烛，比卤素大灯亮度提升300%
LED灯:光谱几乎全部集中于可见光断，发光率可达80~90%，输出6200流明，相当于6200根蜡烛
效果方面分析(从好到差) :
HID改装原厂LED升级型卤素灯= 替换型HID普通卤素灯效果上来说，即使是原厂LED，
单从亮度上说也是比不上好的HID改装，当然高端的原厂LED的智能性是HID改装无法实现的。
升级型卤素灯效果会好于大多数替换型HID和替换型LED，但不排除比较好的替按型HID可以超过升级型卤素灯，
LED同理，但考虑到车型适配，我把升级型卤素灯排在了最前面。最后说一个极端的情况，
现在替换型LED如果买到差的，效果会比普通卤素灯更糟，不要怀疑，这种产品现在在外贸市场非常多。
经济性分析 (从便宜到贵) :
普通卤素灯升级型卤素灯=替换型HIDHID改装原厂LED这个就没什么好说了，
HID改装要买透镜，气灯还需要较长的改装工时。而原厂LED因为基本非国产甚至涉及智能系统，价格不是同一个高度。
寿命(从短到长)升级型素灯普通卤素灯，HID改装，原厂LED灯，因为替换型HID的质量上下浮动太大，所以寿命真不好预测。
替换难易度 (简单到复杂)
普通卤素灯=升级型卤素灯替换型HID，HID改装原厂LED前两个直接拔出来替换即可，替换型HID则要找地方固定安定器，不过也是个人能DIY的范畴。后面两人就不是自己能DIY的(动手帝除外) ，因为会需要专业设备和知识。
总结：
其实这三种车灯也都是各有优劣势，但是不得不承认的是，随着成本的降低，LED车灯将很有可能会成为日后的主流，LED的使用寿命、亮度高等优势对于我们日常用车非常有用。而卤素灯，虽然如今地位大幅下降，但便宜的成本与制作简单的特性，还是让它成为许多中低配车型的首选用灯。看了上面的分析大家应该对卤素灯、氙气灯、LED灯的优缺点都有了一定的了解，大家根据自己的使用情况参考选择吧。

In fact, it can be seen from the new cars launched by the major manufacturers that halogen lights = low, xenon lights = medium and LED = high, so are halogen lights really that bad? What is the strength of gas lights and LEDs?
Halogen lights advantages and disadvantages
Halogen headlights are a new generation of incandescent lamps, filled with bromine iodine and other halogen elements or halide tungsten lamps.
When energized, electrical energy heats the tungsten filament to an incandescent state for luminescence, converting electrical energy into heat and then into light energy.
Advantages:
1. Low cost and simple to produce.
2. Low colour temperature, good wearability.
3. Fast opening speed.
4. Better penetration with reflectors in rainy and foggy weather,
Bad disadvantages:
High temperature, poor durability, low brightness.
Advantages and disadvantages of xenon lights
Xenon lamps (HID) work on the principle of high pressure gas discharge lamps.
The 12V voltage is boosted to an ultra-high voltage of 23,000V, which is used to excite the gas that fills the quartz tube to make it glow.
The voltage is then converted to around 85V, which provides a steady and continuous supply of light to the xenon bulb.
Advantages:
1. High brightness: generally three times brighter than halogen lamps
2. High colour temperature: HID lamps can produce a colour temperature of 4000-12000k, close to the colour of midday sun, which is the most acceptable and comfortable to the human eye.
3. Long life: a set of HID discharge lamps lasts approximately 3000 hours
4. Less power consumption: the power of HID is generally only 35 W, while the power of ordinary lights is generally 55 W.
5. High-class, generally only equipped in the high-end models, at night to improve the status and face of the symbol. Disadvantages
Disadvantages:
1、High heat generation, will reach 300-400 degrees, the light is easy to be baked
2. There will be a delay
Advantages and disadvantages of LED lights
LED is the abbreviation of Light Emitting Diode, the Chinese name is one by one light emitting diode, PN junction.
They are now often used in the role of light boxes, signboards and indicators and backlights for various appliances, and are also often an important component of car tail lights, high mounted brake lights and daytime running lights. And ED headlights are luminaires that are manufactured using LEDs as a light source.
Advantages:
1, long service life:The LED components currently used in cars can basically reach at least 50,000 hours.
2, good durability, not easy to break impact resistance and good shock resistance.
3, fast response time.
4, high brightness.
Disadvantages:
Although they have been declining, the cost of LEDs is still high, so they will generally only be found in mid to high end models
Practical analysis of halogen, xenon and LED lights:
Halogen: High penetrating power, 500 hours life span
Xenon: now the mainstream, good brightness, can not be stable, now the technology is mature, stability, much better, but the modification usually have to destroy the car body, life 3000 hours, cold light, rain and fog days penetration is weak.
LED lights: energy saving, bright enough, long life, generally can reach 5000 hours, technical stability, non-destructive installation. From all aspects of cost performance led lights are the most practical.
Halogen: in the dark, yellowish halogen light is not so conspicuous, the maximum output of 1200 lumens, equivalent to 1200 candles
Xenon: 4500 lumens output, equivalent to 4500 candles, 300% brighter than halogen headlamps
LED lights: the spectrum is almost entirely concentrated in the visible light break, the luminous rate can reach 80~90%, the output of 6200 lumens, equivalent to 6200 candles
Analysis of the effect (from good to bad) .
HID retrofit original LED upgrade halogen lamps = replacement HID ordinary halogen lamp effect, even if the original LED
In terms of brightness alone it is no better than a good HID retrofit, but of course the intelligence of the high-end original LED is something that cannot be achieved with HID retrofit.
Upgraded halogen lamps are better than most replacement HIDs and replacement LEDs, but this does not preclude the better replacement HIDs from outperforming upgraded halogen lamps.
The same goes for LEDs, but I have put the upgraded halogens at the top of the list for model fitment reasons. Finally, in an extreme case.
Nowadays, if you buy a poor replacement LED, the effect will be worse than a normal halogen, don't doubt it, this kind of product is now very much in the foreign trade market.
Economical analysis (from cheap to expensive).
Ordinary halogen lamps upgrade halogen lamps = replacement HIDHID conversion of the original LED this there is nothing to say.
HID conversion to buy lenses, gas lamps also need to be more
