No that's fine. I've never done it as I said so I can only go on theory but, I believe what happens is; (with a Kufatec wiring loom)
By default;
1) The Xenons will work for dipped beam and halogen would work for high beam on both forward and pull back on the stalk.
2) The in-car levelling adjuster will adjust the beam (he thinks..???)
If you run a wire from the wiring loom to the CEC under the steering wheel, you can have it so when you flick the full beam switch forward, you activate the BiXenon functionality.
You can also then install self levelling if you do desire.
