Default Bi-xenon E-code?

Is this for real, the bi-xenon part? I can't seem to see a flap that could open or close in the picture they show at www.vagparts.com. Could anybody who have these post a picture of the high-beam?

Another question: what happens to the E-code city light in Canadian-spec cars? Unless I'm truly mistaken, our blinkers are not on all the time stock: we have our fogs on all the time instead.

Default Flap?

I didn't know there was a flap...I assumed Bi-Xenon is just low and high beam Xenons...and the high beam would physically look the same as the halogen high beams...except with Xenon bulbs/ballasts.

Default Xenon has to stay on all the time - so to do high beams

car mfrs either use a motor to move the focal point or a flap to cover the bulb.

Default needs to have a flap to keep them covered. Xenon gas takes a little longer to fire up than halogen

so the bi-xenon lights actually keep the high beam on all the time and covered by the "flap" in order to keep them covered. when you flash someone the flap retracts or opens up kind of like a photo lens aperture and allows the high beams to shine thru.

That's pretty crazy...why don't the low beams work like that?

Default take longer to fire up and would not work in a flashing situation as well as the fact that

xenon bulbs burn out faster if you turn them on and off in a quick flashing fashion, this causes excessive wear on them

Default basically when you turn on the low beams they take a second or so

to actually ignite and reach the desired level of illumination, they start out very blue then turn more white as they warm up, they do essentially work like that. the high beams would just bnot be good to flash anyone if the took a second to fire up

Default Usually bixenons use the same bulb as the low beam.

They just cover the top part of the low beam with the flap (which usually doubles as the auto leveler).
