Another important factor about HID lights is that they emit colored lights. The colored lights are represented with numeric coding. The coloring function of these bulbs depends on the heat generation. You can get blue, yellow or violet colored lights from HID to name a few. This illumination technology is widely used by many automobile manufacturer brands. HID kits ensure greater and clear visibility for the automobile drivers. The installation process requires no drilling or other modifications. In fact, this HID lighting systems are proven to reduce significantly the occurrence of eye fatigue and enhance concentration on the road. The life duration of such bulbs is higher than normal incandescent lamps. They emit bright and clear light. HID kits increase the visibility up to 70% more than halogen bulbs and provide 3 times more illuminated coverage than ordinary lamps. The service life period is up to 10 times longer than any other lighting systems. Vehicles that have HID kits are required to be equipped with headlamp lens cleaning systems and automatic beam leveling control. They reduce the tendency for high-output bulbs to cause high levels of glare to other road users.High Intensity Discharge lights get their name from the electrical discharge that produces the intense white light. HID bulbs don't have filament. The light is created by bringing the arc between two electrodes, it stimulates a mixture of Xenon gas and metallic salts, producing the bright light. The first xenon lights were introduced in 1991 for Europe and in 1993 for the USA. HID bulbs produce greater luminance and luminous flux than halogen ones. Studies have demonstrated that drivers react faster on the roadway with good HID lights rather than halogen bulbs.
