HID headlight, or High intensity discharger, is the upgraded lighting system
for your original halogen headlight, it comes with many decent features compared
to the halogen lights. The main advantages are the high light intensity provided
by the HID lamps and a low power consumption. HID lights are getting more and
more popular for automotive car headlight system, most of the new car models
are equipped with the HID lamps, and it seems that the HID lights will keep
replacing the original halogen lights in the future.

As mention above that the HID lights can provide a higher light intensity with
a lower power consumptions, there are some other factors to make it so popular.

1. Color temperature: HID has a range of color temperature measured in K, which
is a measures of the color for the lighting output. The common color temperatures
are 3000K (Golden Yellow) , 4300K (Bright White), 5000K (white), 6000K (Crystal
White),8000K (Crystal Blue), 10000K (Aqua Blue), 12000K (Purple-Blue). While
5000K and 6000K are the most common color temperature for HID lamps and its
widely accepted by most drivers because of the natural sun lights it provided.

2. Lifetime for HID lights: Most of the HID lights can last for around 2500
hours.

3. Lesser power consumption: HID lights can generate 3 times greater the light
intensity compared to the original halogen bulbs with even lesser power consumption.
You can save it up to 25% on the power.

There are something you should consider before purchasing a HID conversion kits,
check your bulb size with refer to your car model, choose the correct color
temperature, 5000K and 6000K are widely accepted, if you are planning to use
the 12000K (purple), be noticed that it's illegal in many countries, those color
temperature are always used off the road.
