I have these projector headlights with H4 bulbs and a black background. I tried them for the first time and they are really dim and not bright at all, I could barely see! Anyways, I bought these headlights and they are dim there is a little bulb under the h4 headlights with wires out of them if I wired them would the light get brighter? I also bought the recommended wiring harness supposedly supposed to make it brighter. Will the harness be okay, or should I wire the smaller bulbs too?
