I found them on ebay and i asked the seller for some up close pictures to see if indeed the halogen bulb was over the ballast and in the close up pictures of the ballast the halogen filament and the arc gap of the ballast seemed to be lined up very closely. So going by what backinblack has been posting it should work pretty good. Thats really all im looking to do is pass inspection but i want the beam to be somewhat usefull. Oh and zef_66 i found a lot of them to choose from on ebay. If you have trouble finding them i can send you some links.
