Question Xenon and Bi-Xenon

What is the different between Xenon and Bi-Xenon light??

Is our's one Xenon or Bi-Xenon??

As most of the Xenon light I saw, the light came out with a bit of purple, but as I seen the picture of RX-8 with the lights on, it's came out with a bit of green rather than purple.
Why is that??

bi xenon is used in bmw

meaning the high and low beams are both xenon

and there's only one projector instead

it can use either an apreature (like camera) or it moves the distant and location of the bulb within the projector housing

thisi way, the high beam would come "on" instantly and wouldn't have to warm up like the low beam

Does anyone know if the rx-8 has a 5k or 6k xenon light? I believe the 5k is a pure white light like in the acura tl/cl cars, while the 6k is the purple/white light like in the s2k.

BMW high beams are halogen.

It's against the law to have xenon high beams. Bi-xenon means something else though... I'm unsure of exactly what

I think you are right.

I pulled this from the Saabnet, since the 9-5 and 9-3 was once on my short list, before I decide on the wonderful RX-8. :D


What is bi-xenon lighting?
Unlike conventional halogen bulbs, which use a glowing filament and reflectors to direct the spread of light, xenon lighting uses a bright, white gas-discharge lamp. Xenon lights work on alternating current (AC) while halogen bulbs are powered by the battery's DC current. To provide the xenon lights with AC, an electronic ballast (starter module), with a high-voltage start-up, transforms the normal voltage into AC. This provides significantly more power for lighting.
Until relatively recently, only low-beam xenon light systems have been on the market. They used a combination of xenon lighting with its projector modules for low-beam work and halogen bulbs with reflectors for high-beam situations, simply because the xenon projector modules just weren't big enough to work effectively on high beam.
However, two years ago, the first bi-xenon lights were made commercially available, with a projector module featuring a shutter which rises to reveal the whole lamp on high beam. That's when Saab decided to incorporate the lighting system as an option on the new Saab 9-5. However, the bi-xenon headlamp unit still retains halogen bulbs with separate, larger reflectors for the headlight flash function, an important safety feature.
Here is the full scoop on the Xenon's, CLICK HERE, according to saabnet.com.

Hope this helps.

i don't think i am wrong
bi xenon is single housing for sure
i think you are right on the part of the high beam being halogen
which is permently on, creating the "angel eyes" on the 3 series

and the "apretures" i was refering to maybe block the xenon and/or use some kind of reflectors to project the high beam

for sure, pulling the high beam stock does NOT turn on or off either lights

go to the middle regarding "adeptive headlights"

4100k is the brighest (or closest to real sunlight). As you move further away from 4100k such as 5000k, 6000k, 12000k, companies use filters to create purplish or bluish light by filtering only the blue colors out. The higher the rating, the less the intensity of light, but more distinct color. I believe the highest real rating is made by Philips (whom manufactures most all OEM HID systems for car makers) and is 6800k or something.

Daylight is closest to D65 or 6500K. At night this looks very blue (or purple) do to all of the other light sources (sodium, incadescent, halogen, etc.) all being so yellow, so the best thing to go with is 4100K. Also the extra blue of 6500K can be more blinding because it excites the sensitive s-cones of the eye.

From www.bmwusa.com as a 330 feature:

Xenon low-beam and high-beam headlights with auto-leveling

My '98 540i has halogen high beams, but the new 3-series BMWs have Xenon high and low beams in Canada.

Since the web site is the US one, I assume that it is also true in the US.

Has anone checked out the RX-8 high beams?

I don't think the high beam for RX-8 is Xenon

Bi-Xenon is a bad name for the lighting system.
The arc discharge capsule (HID high intensity discharge) makes light for the low beam, but when you flip to high beams; the halogen high beams light up very far down the road (very focused, like 'pencil beams') the cutoff shield in the low beams drop down via solenoid (down-makes the cutoff rise up, remember the plano-convex lens is converging) now the low beam light, illuminates the low beam area, and now the 'mid range' area, and maybe where the traditional high beams used to light up-if the 'bi-xenons' have automatic leveling and range control.

I got this from mercedes-benz website

it say
Bi-xenon headlamps, which are able to offer the outstanding luminous power and range of the xenon bulb in both the low beam and high beam settings
