I too have read the mixed reviews and hopefully my install will go smoothly. If I was going to do the conversion on my headlights, I would not go with an ebay deal, but would go with a reputable company. I am not sure if I would trust these to be reliable enough to be my everyday lights, it would suck to be stranded with no headlights and then on top of that, not having good customer service to get them fixed.
I am going to start retrofitting tomorrow and hopefully have it done by Sunday evening. We'll see if that is possible with these kids.
