The headlight is from a Honda Hornet 600 >2003. As far as I know the only single round headlight with two sepperate reflectors for high and low beam. I think I've seen some unknown Italian bike with a similar design but there are probably only 300 of those made so that's not an option.
Here are some more pics, first the headlight with the two xenon bulbs.

High beam
Different angle
Here's what the cyclists see
I have changed my electrical circuit so both low and high beams are on when I switch to high beam, by using two relays. If it's set to low beam it runs mostly through the original circuit. I've used this with the original H11 bulbs and it worked fine, only thing I had to change when installing the xenon bulbs were the connectors for the bulbs and changinge the fuses from 5A to 7.5A because the xenon bulbs use about 6A a piece when starting up (5 seconds) and then go back to about 3.5A.
It's probably illegal in The Netherlands as well, but so are open end can's. As long as you don't over-do it the police won't make any problems. Unless they haven't reached their quota yet
