What Are HID Lights?

HID (High-Intensity Discharge) lights are now becoming popular day in and day out. You use HID lights on the headlight of your car. So, now what is this HID light?

A HID light switches on when there is an electric discharge between two electrodes. These two electrodes are present in a glass tube. In the tube, you will find noble gas, i.e.xenon and metal salts.

The xenon gas can warm your HID bulb within a few seconds, which other gas cannot do. So, in brief, you can say that HID light converts electricity into light. But to supply voltage and continuous flow of current to HID light, you need another electrical component, i.e.ballast. So, in an HID kit, you will find both HID bulbs and ballast together. A ballast is mandatory if you are installing an HID bulb in your vehicle.
