With cars you know that the normal headlights just don't work. They are very effective in using as little electricity as possible, however, in most cases they are not actually bright enough to see the road and avoid possible hazards like hitting an animal. It is because they are so inefficient that people generally buy HID conversion kits to replace them.



HID stands for high intensity discharge. Using the HID headlights can put out more than 5 times the amount of light than you would get from your average halogen headlights. This means that you see more and can find it easier to avoid any problems.

HID is not your usual light bulb. With most light bulbs there is a filament surrounded by inert gases like argon that work to keep it from catching fire. The filament is attached to two long metal rods. As electricity pulses through them heat is produced, and eventually there is enough heat to cause enough visible light for a person to use. The halogen light bulb usually used in car is a little more advanced. It uses the same filament but encases it in quartz. It also fills envelope with halogen gases. The halogen gases work buy re-depositing atoms on the filament when the temperature is high enough and the halogen gases combine with tungsten vapors from the filament. This allows the light bulbs to burn at a higher temperature and they actually last longer as well.

There are lights that are more efficient than halogen lights though. HID lights are both brighter and take up less energy. Instead of using the usually filaments HID lights use gases to produce the light we use. HID headlights that you get with the use the same high pressure technology that we often see used with street lamps. The gases used are often Mercury and is very close in design to a mercury vapor lamp. There is one little problem that scientist ha to work out though. Like with florescent light bulbs, these would take a long time to warm up and actually become bright. To help fix this there is xenon and a special controller that is used.

Back in the day HID headlights and were only offered as an option for those high end luxury cars. Today however, though they are still a little expensive, they are becoming more and more available as they are produced in greater quantity. They are becoming more popular because of the light benefits that people get out of them at night. To give you an idea as to just how beneficial the HID kits can be to your car, there are airplanes that use HID lights because of how bright they are.

Anybody who owns a car can benefit from HID conversion kits. This is especially true for people who generally have a hard time with seeing at night, which makes it harder to react in dangerous situations, including the elderly. If you chose a good quality HID light then you will improve your night time visibility and help to get you and your family where you need to be with less risk.
