A little background, these lights did not flicker like this for the last year or so that they have been installed. I have them tied into my high beams using a relay so that when I pull the high beam on, they come on and they also can be turned off separate of the high beam. I thought maybe the relay was bad so I replaced that. Not the issue. I also have a dual battery set up with a hell roaring kit. This allows me to separate and combine the batteries with a flick of the switch. I have two newer agm batteries, when I combine the batteries the flicker stops. I've had both batteries tested and both came back ok. Anyone have any idea other than pulling the loom and replacing?
