Headlights have a huge impact on a person's night driving experience. Whether you can see far enough of the road ahead is not a matter of comfort, but of safety. Freeways are easy, but once you get onto a low-priority road, you have to be able to see what's ahead. One of the most popular lighting technologies in today's car headlights is HID car xenon lights.
HID is now an improved version of earlier tungsten technology. It's actually a new type of lighting. High-intensity discharge lamps are gas discharge lamps. Light is generated by interdigitated electrode discharge transport. When they do this in an inert xenon vessel, it becomes an HID xenon lamp. Comes in a translucent or clear tube. Significantly brighter, their lighting performance is even better than LED lights. While they may not last as long as LED lights, they last 5 times longer than halogen lights at about 10,000 hours. Xenon bulbs are much brighter than halogen bulbs, which helps you see farther and better when driving at night. Xenon bulbs can also produce a higher color temperature than halogen bulbs. Halogen becomes non-road legal when it reaches a color temperature of 4300K and is limited in producing blue light. HID, however, can easily achieve higher color temperatures while maintaining road legality. This means you can get a very intense, stylish ice white/blue light on the road with xenon bulbs.
A final advantage of Xenon HIDs is their longevity. Xenon bulbs last much longer than halogen bulbs, which means you don't have to worry about replacing them as often. This has the potential to save you money in the long run. However, be aware that individual xenon bulbs are more expensive than individual halogen bulbs.
