What does a headlight control unit do?
Its primary purpose is to control the intensity of your car headlight. It also controls the intensity of the bulbs so that they are not using up all your power.
What does xenon bulb mean?
A xenon bulb is a specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light that closely mimics natural sunlight.
How do xenon bulbs work?
Here’s the basic science behind how xenon lights work: The electrical current hits the electrodes, creating a powerful electrical force. The electricity causes the xenon gas atoms to split into smaller parts (ionization) The electrodes heat up, and the heat causes additional light.
What are xenon lights used for?
Xenon is a gas – it’s used in HID (high intensity discharge) lights. These headlights are very different from conventional halogen bulbs, and will not work in a standard headlight socket. You can find bulbs on the market that attempt to mimic the color of the light produced, but these are not xenon bulbs.
What does a xenon HID light bulb do?
When the lamp is turned on, the ballast provides a surge of higher voltage to the lamp. This helps establish an arc between two electrodes on the lamp, which is what causes HID bulbs to light up. The other key function of a ballast is to keep your lamp running and make sure the output is steady.
How does the fourth generation xenon bulb work?
Fourth-generation xenon HID systems can deliver up to 30 kV of high-voltage pulse. This component controls xenon bulb start-up, allowing it to reach its optimum operating phase quickly. Once the bulb is operating at its optimum brightness, the ballast controls the power that goes through the system to maintain the brightness.
What are the advantages of using xenon headlights?
Advantages of Xenon Headlights. There are several advantages to using xenon HID headlights over conventional halogen bulbs. Brighter, More Natural Light; A 35-watt xenon bulb can produce up to 3,000 lumens. A watt-comparable halogen bulb can only muster 1,400 lumens.
Why do I need ballast for my xenon lamp?
Without a ballast, the lamp would draw too much power, causing it to burn out quickly – sometimes even within a few minutes. The ballast prevents this from happening and ensures you get the benefits of the lamp’s full lifetime.

How does a DC converter work on a xenon bulb?
A DC converter generates the required voltage for the electronics and the bulb from the vehicle electrical system. The bridge circuit supplies a 300-Hz alternating voltage to operate the xenon bulbs. Several control and safety circuits are integrated in the device. Several control and safety circuits are integrated in the device.
What kind of voltage does a xenon light need?
Voltage must be at least 9 Volts. If the voltage and ground supply, as well as the xenon bulb, are OK, the cause of the fault is a faulty ballast. Xenon headlights look sophisticated and provide the vehicle with a top-class feel. This causes some drivers to upgrade their vehicles with xenon lights.
