I wanteds to know if someone can explain to me the difference between xenon and bi-xenon lighting for the lr3 i know that some models the lights have adaptive lighting however i was under the assumption that they were both the same.

 

I always though the bi-zenon was the dual set of hi/low lighting.

 

yea from all my other car forums the term bi-xenon meant that it was both Hi and low, I think the lens flips up to shine the light up higher, is my understanding...there are fake Bi xenon systems that run a second Halogen bulb as the high....

 

In most cases there's a metal plate that blocks the "high" portion of the beam, and a separate halogen lamp serves for highs. In bi-xenons, i.e. with high beams, when switch to highs, a solenoid moves the plate away . But since even modern xenons take some time to reach max output, there's still a separate halogen for "flashing".
The plate, btw, is the reason the low-beam xenons have such a sharp cut-off (not always, though, as some manufacturers like Audi installed lenses with radial notches to blur the light, to comply with US DOT standards).

Add the swivelling function for adaptive lighting, and you have a headlights that costs you $$$ if replacement is needed.
