How Do Xenon Headlights Work?

Xenon headlights (xenon brenner) are identifiable by the bluish light they produce. This technology, introduced in the early 90’s, uses light bulbs that contain xenon (rare gas) that will illuminate under the effect of a high voltage current applied between two electrodes.

If you drive a car with xenon headlights, you’ve probably noticed a distinct difference compared to “traditional” headlights. Xenon headlights illuminate better while consuming less than a halogen bulb. Economy that you will not find in the overall fuel consumption of the car. It would have been too good.

Xenon headlights offer several advantages

The main advantage of xenon headlights (xenon brenner) is that it gives you better visual comfort if you drive at night. The light produced by these headlights is similar to the light emitted by the sun (the wearing of sunglasses is not mandatory) and will give you the impression to see as daylight.

Another advantage is that xenon headlights are designed to last as long as the vehicle on which they are mounted. Your wallet will certainly appreciate, especially since Xenon headlights are mostly available as an option and are very expensive to buy because they require a specific electronics and a correcting plate so as not to dazzle motorists. ‘in front.

Many motorists want to install commercially available xenon headlights to rejuvenate or customize their cars. If their purchase is simple, the regulation is so strict that it is impossible for you to fully respect it. In addition to the automatic trimmer mentioned above, you will need to install headlamps on your vehicle.

Given these constraints, if you want to change your headlights to the benefit of “fake” xenon headlights (xenon brenner), the easiest way is to see your dealer and order a new vehicle.

Principle of operation

Discovered in 1898 by W. W. Ramsay and Travers called Xenon gas will be integrated into a discharge lamp as around 1999. Its operating principle is based on the fact that this gas lights in contact with a current greater than 20,000 volts when applied between two electrodes. Unlike the iodine lamp commonly used on vehicles since 1964, the Xenon lamp produces a brighter light and has three times more power than the latter; moreover its consumption is lower: 40 to 45 watts. Different from the conventional halogen bulb, the optical Xenon do not emit enough heat to melt snow or a thin layer of ice which adheres to the headlights; they must also have spotlights.

There are different Xenon lights or xenon brenner. For example, bi-xenon, low beam and high beam headlamps with or without a directional system for superior visibility, especially when cornering. This mechanism synchronizes the orientation of the light beam with the stopping angle of the wheels. Generally, a Xenon headlamp is equipped with headlamps and a stabilizer (trimmer) to avoid dazzling other drivers.

Advantages and disadvantages of Xenon headlights

The Xenon headlamps illuminate a wide field of vision and produce a bluish light that is close to natural daylight, making driving easier. Another advantage, the life of this kind of lamps is very long: 3,000 hours or a million kilometers.

Even if we rarely have to replace them, Xenon headlights are quite expensive: for example, about 320 euros for a Passat. It must be said that the technology they are provided with is complex and expensive to produce (especially when associated with the steering mechanism). As for the projector washer, it is quite difficult to install.
