CF650NK Bi Xenon or Xenon upgrade? HID projectors or not..?

[Wald0]

So should i use Xenon or Bi xenon? as far that i understand Bi xenon has long beam and short while Xenon uses only short beam.

That should tell me that use Bi Xenon!

Second obstacle is 650NK head light construction as it already uses projector although this is halogen projector i could use it and not install HID projectors
while HID projectors are wider than Halogen normally and disperse light more wider (thats what i have been reading)
While normal reflectors would produce clare, i'm not sure if halogen projectors would produce any or at least very little clare.

I will ride tomorrow to market and look if they have some Bi xenon on sale.

BTW: Who can say if those "made in china" HID/Xenon projectors work any better that 650NK original ones? although they are made in china too
