Thanks again.
If you have the single beams, with the halogen bulb piggybacked on to the xenon bulb, then in theory, the dual beam should work with what you have. The power sent to fire the halogen hi beam on the single beam xenon, is the same power that controls the solenoid that shifts the bulbs position in the hi-lo kits.
It would be a good idea to verify this with Joseph or someone who is better versed in automotive electronics than I am, but that's my understanding of how they operate.
Also, I've ordered replacement bulbs from ebay before, they didn't have the same connections as my old bulbs, but it was a simple cut & splice to fix that...
