LED halo upgrade with factory Zenon lamps

[AussiE53]

Sorry if this question has been asked before. I did search.

I have purchased some H8 LED bulbs and done the usual YouTube "how to" search and nothing matches up. Even the owners manual doesn't make sense.

I have an Australian delivered 09 E70 with factory Zenon driving lamps. I have been told that the halo rings are powered off the Zenon bulb (ie the outer most lamp) that has an adjustable shutter that directs the light in different directions.

Soooo...... Is it possible to get my halo rings white instead of yellow?

If so how?

Thanks in advance. Cheers
