BMW’s xenon headlights use high-intensity discharge (HID) bulbs that produce light by creating an electric arc between two electrodes in a quartz glass bulb filled with xenon gas. With a bi-xenon system, when the low beams are on, a shield is placed in front of the bulb.

What is Bi Xenon?

Bi-Xenons are dual-beam bulbs (one bulb for both the low and high beam function) designed for dual-beam headlight systems. Xenons are single-beam bulbs (one for each the low and the high beam function) designed for single-beam headlight systems.

What property of xenon make it good for use in car headlights?

brightness
The Sciencey bit The xenon gas fills the chamber in which the contacts sit, and amplifies the brightness of the light, helping it to quickly reach the temperature necessary to emit an intense beam.

Can you touch xenon bulbs?

You can actually touch xenon bulbs. With halogen lights, you shouldn’t touch the bulb itself, because the oil from your hands might significantly reduce its lifetime. There is no high pressure danger with xenon light bulbs, as there is with halogens.

What is difference between xenon and halogen?

Xenon can last 10 times longer than Halogen. Xenon produces a cleaner, whiter light than a 55w Halogen bulb. Xenon light is whiter, bluish light whereas Halogen is more yellowish. Halogen bulbs burn hotter than the same wattage Xenon bulb.

How do I know if my car has xenon headlights?

Turn your car on, turn the high beams on, stand in front of one headlight and stare straight into it for 10 seconds. If you are only partially blind, its a halogen. If you are completely blind, its xenon. Now that we know you do have xenons, you should definitely look into lux before ordering your angel eyes.

What color is xenon?

blue
A colourless, odourless gas. It is very unreactive. Xenon is used in certain specialised light sources. It produces a beautiful blue glow when excited by an electrical discharge.

Is xenon brighter than halogen?

Light output Xenon headlights are more than twice as bright as halogen ones – 3200 lumens compared to 1500 lumens – which is why xenon headlights illuminate more of the road than halogen ones.
