i tried to put oem maxima hids into my 99 civic halo projectors. the hole was too small. there wasn't enough clearance, for the oem hid bulbs. I emailed a few sellers on ebay about their h1 kit (because the halo kit converts civic h4 into h1 bulbs for the projectors). Most of them said that it won't fit. but there was one that said it did, and he wanted $400 for a 8000K kit. I'm still in the process of finding out more about the mod. I really dont' want to tear up a pair of $180 projector headlights to try to retrofit audi projectors in them...any suggestions?
