I recently got rid of my factory headlamps and replaced them with the Hella Vision Plus 7" Round conversion. I had to change the wiring harness because the factory lights would not interchange and the new lights use an H4, HB2, 9003 bulb. Now when I turn on my lights, the lights come on, but I think they are on high. When I switch to the high beams, my lights dim and they barely work. Does anyone have any suggestions or solutions to this problem?
