How Do Automobile HID Lights Operate?
HID Basics HID, or high intensity discharge lights, are a type of light that uses an electric arc to create power. Arc lights like this have been used to light stadiums, streets and parking lots for a long time because they create more light using less energy than most other types of light bulbs. Because they’re somewhat expensive and require sophisticated control circuits, they’ve been late to catch on in cars. You can spot an HID automobile light by the bluish tint. HID Structure Inside the HID lamp is a small tube of fused quartz. The quartz is much stronger than gas and has good insulating properties that stop heat from leaking. This strength is necessary to contain the gas inside. HID tubes contain xenon gas and compounds called metal halides pressurized to many times the atmospheric pressure. The lamp is powered by two electrodes positioned close to each other. Like other automotive lights, HID lights also have reflectors and lenses to focus the light at the road ahead. HID Funct
