I have this host that’s been lying around for ages and I’m trying to figure out what type of automotive lamp this takes as I’m planning to do a HID thrower project with it. I can’t remember for the life of me which bulb I took out of here. I think it’s an H3 or H7. The host is an ifixit tools 3 million candlepower spotlight 2005 or so vintage. Any help is appreciated.
