LED headlights and xenon lights
 

Got myself the LED headlights for my car a while ago, decided to get the HID kit and put it in for the low beam. I got the H1 light bulb but that one is like too fat to got in the housing. Does anyone know what the light bulb should be?? The original one in the head light is a H1 too, but the xenon one does not fit. Please help
