Need some help with the bulbs that i got. They are the H3c bulbs and im trying to figure why it wont turn on. I know it has two connections on the back of the bulb. I figured from the lexus I took them off that one of those connections is a ground and the other a positive. So I tried wiring them up the same way I had the original H3 ones up and they dont work. So I went and pluged up the old H3 bulbs and they lit right up. Maybe im doing something wrong any help would be appreciated. Thanks
