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?

It's also only the low beam the goes out. The high beam always works, even if the low beam is out. I'm avoiding having to hardwire the connection.

Have you tried putting the good (driver's side) headlight into the faulty harness?

- If this works fine >> your issue is jeep (passenger) harness. Repair/replace.
- If this fails >> send JW headlight back for warranty replacement.

I have not heard of this issue before, and have experienced zero issues since replacing mine a year ago w/out dielectric grease.

Yep, and the issue persisted on the same side of the Jeep. It took just about a year for this to happen. I'm also in the northeast and corrosion happens fast with all the salt. I might just put terminals on both the light and Jeep and connect it that way.

@BlackRubiHR - Your profile says its a 2016. Why not take it in for service and have them replace the cable for free? I know my dealer (Southampton, NY) sells the JW Evo2's and wouldn't hassle about them being non-stock lights...maybe a dealer will look past, acknowledge the issue and replace cable for you?

I'm also in Northeast, and drive mine regularly on the beach (including in the surf/wet sand) and no corrosion issues. I'd hope a dealer fix would be a permanent solution for you.

I had the same problem on my 2014 my power steering reservoir was cracked and leaking it was replaced under warranty but the fluid had caused the headlight plug to fail. I baught a 5.00 jeep side harness and replaced it no problems since
