The HID "bulb" may fit, but you going from a point source (a small hot filament) at known location to a diffuse source. The optics in the headlamp typically are not designed for that. The cut off is screwed up. That is the key. You create glare for oncoming drivers. Guys are making a quick buck selling this "cool" stuff. Great way to make money. Provide an truly independent evaluation that it can be correctly and safely. If someone has this I 'd love to see it. It would be great if it could be right and not costing a lot. Every day I see a bunch of bad conversions.
