HID kits are headlight conversion sets which include all the elements that allow you to change your car or motorcycle headlights from traditional halogen bulbs to xenon or HID bulbs. HID stands for High Intensity Discharge and xenon is the gas contained in the bulbs.
What are HID kits?
There are a number of elements contained in a HID kit consisting of two bulbs, dual or two single ballasts, starter, holders, wires and connectors. Each and every kit consists of an instruction manual as most people are able to do the conversion from halogen to HID bulbs themselves. Most of the new HID kits include slim digital ballasts, which replace the older magnetic ones. You cannot use your ordinary light system with xenon bulbs as a HID kit utilizes a really different mechanism.
Installing the kits
When installing HID kits you require to use latex gloves so that you do not touch the glass of the bulbs with your fingers. This is because oil from your skin can shorten the life of the HID bulb. You want to make sure you fasten the ballasts and starter securely to the automobile in a appropriate mounting spot so that all the wiring can reach without having fitting too closely. Once you have unplugged the halogen bulb and removed it from the headlight holder, take the plug and plug it into the starter. Then plug the starter into the ballast and plug the new HID bulbs into the headlight housing, which should match in the same way as the halogen ones you removed. Lastly, the ballast needs to be plugged into the bulb to complete the circuit. You might require to adjust the headlights just before the kit is totally functioning.
How they perform
Taking the signal from the starter, ballasts provide the essential voltage to ignite the HID bulbs and handle the current to the bulb. When the bulb receives the power from the ballast, it energizes the xenon gas in the bulb producing a white/blue light, the colour getting regulated by the Kelvin color/temperature of the kit.
