The projectors are Hella, the ones found in the BMW 5 series (E39, not the new ones), the X5 and the Mercedes E55, as well as other cars. I'm actually taking a bunch of pictures, documenting the entire process. Give me a few days, but I should have a pretty good write up by the time everything is said and done.
Today I tore into the other lamp and got it all converted, ran into a few hang ups but got most all of them settled. All the wiring is finished and everything works, but I had some bad glare problems with my projector shroud design so I ended up having to rework those a bit. After reworking them I found that the way I did it is making it so the bi-xenon solenoid isn't able to trigger anymore, so I need to take them apart yet again to fix that. Everything should be finished by mid tomorrow I'm hoping, so long as nothing else goes wrong.
One thing that I'm a bit dissapointed in is the fact that flashing your brights also flicks on the low beams, not just the highs. This means that after doing the conversion, flashing someone turns on the xenon lamps and turns them back off right away which is terribly hard on the entire system. You usually need a minimum 10 seconds or so of light-off before shutting them off, or you risk hurting the bulb or the ballast. Basically note that if you're considering doing this, you won't be able to flash your highs anymore unless you low beams are already up and running. If you leave your headlamps on as DRL's (leave the switch on, they shut themselves off automatically after like 30 seconds or a second tap of the lock button anyway) then everything will work normally because the bulbs won't trigger on and off so fast, just the solenoid will go up and down which is what its made to do.
Overall I'm very pleased at how its coming together, but I've been working on it since about 11 this morning until now - about midnight. Needless to say I'm a little tired of it all, which is why I hope everything is finished tomorrow.
Anyway expect pictures of the thing finished tomorrow (hopefully, oh please hopefully) and a write-up mid next week.
