They are Bi-Xenons. You can see the bulbs ons the MK5 standard ones.

Between what?

They are essentially projectors... but they have xenon internals and a shutter inside the lens (which accounts for the bi-xenon name tag)

bi xenons are both high and low beam in one projector unit the image above has one i.e dipped beam high or main beam is normal if that makes sense

I think the mk5 only comes with bi xenon, normally have the ball thing rather than reflector

bi xenon means two that headlight has one i mean you could fit a bi xenon bulb in there in theory but the the bulb to the left is then made redundant which is the high or main beam right? plus you'd have to alter the wiring etc

Bora's that come with xenons are bi xenons both high and low beam on one bulb H4

No such thing as a bi-xenon bulb!

The mk5 xenons ARE bi-xenon!

The lens has a shutter in it to give both dipped and FULL beam! (Bi-xenon)

The halogen bulb in the reflector housing shown on the left in the picture above serves as a FTP (Flash to pass) full beam!

Thats why full beam on a MK5 with bi-xenon are bright - 4 lights on full beam!

Tinners... i thought it was either or!

Push stalk backeards for the xenon full beam (no halogen)

Pull stalk forward for flash to pass halogen.

The bixenon doesn't work on mine because i cannot be bothered to run the extra wires required! [

Could of swore it was all four last time I checked. Will take a gander before I leave work tonight when it's dark.

The Bora has a Xenon projector for dip beam and a second halogen bulb for main beam. The main beam bulb takes the place of the fog lamp in the light assembly, so any Bora with Xenons has no foglights. At least for the OEM Xenon units. If you go with the Xenon / HID kits in the standard headlights then the H4 fitment bulb has a solenoid shunt system which moves the bulb back and forward to give different beam patterns (high & low), similar to the Bi Xenon in question I think.
