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. HID Color temperature refers to the degrees (K), for example golden yellow (3000k), white (5000k), blue (6000k) to name a few. Degrees (K) refer only to the color, while lumen refers to the lighting intensity. So the higher the color temperature (K) doesn't mean a higher light intensity (lumen). Bluish or white light is comfortable and close to the natural light. The recommended types of bulb are 4300k-8000k, because they are extremely bright and don't blind the oncoming drivers.The new HID bulbs are measured by Kelvin's, noted as K on the packaging. The higher the K rating, the brighter the light and the different color it will illuminate. Basically, HID lights come in color levels such as 3000, 4300, 6000, 8000, 10000, 12000 as well as 30000K. The HID lights can vary in their size and model.These lights are available in different colors such as purple and blue to name a few. Therefore, if you are looking for an option to give a sporty look to your car, installing these lights could be the best option for you. Change the dull factory installed lamps with new HID kits.
