Just mounted my Hella 500s on my front bumper and they won't turn on. Very frustrating...we went through and checked most areas so far, but feed is going to the relay to the switch, the switch is working properly and when 'on' properly routes the current back to the relay and to the lights. We are making sure at each point that it's conducting. At this point it's either IN the relay or a problem in the wiring from the relay to the lights themselves. Plan on spending more time tonight troubleshooting this, but with this little info has anyone ever run into something that sounds like this? I know I am not giving much info here, but figured I would through it out there.
