Hide Show. Xenon headlights are comprised of the gas discharge lamp, the xenon ballast, and the reflection and projector-type system. Bi-Xenon means that high beam and low beam are realised by a projection module. This has the advantage that only one ballast is required. This means that two light distributions with a large luminous flux are realised within the smallest installation space. Through the use of a moveable cover, a purely mechanical switch between the light distributions for high beam and low beam is possible.
This means that, aside from the actuating mechanics for the cover, there is no additional outlay for a separate headlamp with its own control electronics. The high beam light also reaches further and the areas to the side of the road are illuminated better. The electronic ballast E ignites the inert gas mixture in the bulb with a high-voltage pulse of up to 30 kV 4th generation.
It causes a spark to flash over between the electrodes of the bulb. The electronic ballast controls the start-up of the bulb so the bulb reaches its operating phase quickly, and then controls the bulb power to a constant 35 W. A DC converter generates the required voltage for the electronics and the bulb from the vehicle electrical system. The bridge circuit supplies a Hz alternating voltage to operate the xenon bulbs.
Several control and safety circuits are integrated in the device. To protect the ballast electronics, a counting circuit ensures that a faulty bulb is only ignited seven times. After this, it is switched off. If the cable connector is removed during operation, the voltage connections are practically voltage-free Xenon headlights look sophisticated and provide the vehicle with a top-class feel. This causes some drivers to upgrade their vehicles with xenon lights.
They buy a set with cables, xenon light sources, and ballast, remove the halogen bulb from the headlamp, saw a hole in the cover cap, insert the xenon bulb into the reflector, connect the electronic ballast with the vehicle electrical system, and the xenon headlight is finished.
But beware! This procedure endangers other road users because of extreme glare and is illegal: The general vehicle certification is rendered invalid, and insurance protection is restricted.
Only complete, type-approved xenon headlight sets including automatic headlamp leveling and headlamp cleaning systems are legal. In Europe, only complete xenon headlight systems may be retrofitted. Related articles.

Xenon vs. What are halogen headlights? How do they work? What are xenon HID headlights? The lights work in three steps: 1. Energy efficiency Compared to xenon headlights, halogen lights require less energy to start up, but more energy to keep going. They also generate large amounts of heat, which is wasted energy.
As xenon lighting uses gas as its energy source, it needs less electricity to generate the light. Lifespan Xenon headlights last a lot longer than halogen ones — 2, to 2, hours for xenon headlights compared to to 1, for halogen.
Cost In general halogen lights are cheaper than xenon headlights to produce, purchase, install and repair. Colour The colour generated also differs. Xenon headlights have a colour temperature of KK, which is a bright white-blue light similar to natural daylight and halogen headlights have a colour temperature of K, which is a warmer, yellow-white light. However, xenon headlights are less effective in foggy weather conditions compared to halogen lights.
Installation Installing halogen headlights is straightforward as they simply click into position. Xenon headlights require a ballast, which makes installation a little more complicated.
