The HID "bulb" in Litronics is used for both low and high beam. The internal motor tilts the projector up for high beam.

Since HID burners are slow to come to full brightness, an auxiliary H7 high beam is also provided. It's halogen so it can be used for flashers as well. You will note that with main headlight switch off, the H7 flasher will work and the HID in the projector doesn't when using flasher lever. This means different circuits for high beam action, not needed with standard halogen light units.

Not as relevant ... cars with HID lighting are required by German law to have standard headlight washing fitted as well.

I added the the tilt function and the dynamic self-leveling capability. The document I created with the instructions is too large to upload on this forum, but if anyone is interested, send me a PM with your email address and I will respond with the instructions. The instructions include information on the headlight washers, but I decided not to install them on my car due to the expense.
