I've had JW speaker headlights for about a year now. When I put them in, I never used dielectric grease. Over the last month, the passenger side headlight has been going out intermittently. Sometimes I can move the harness and it will turn back on, but eventually this stops working. At that point, I have to take the grille off, unplug the harness, and plug it back in. I tried switching the headlights with each other, and the problem still occurs on the passengers side. I used contact cleaner on both sides of the harness. My guess is that harness on the Jeep is the issue but I doubt Jeep will fix that under warranty as I unplugged the stock headlights hence a "modification". Has anyone experienced similar issues or know what to do next?
