2014 JK right headlight over-current issue?

Having a consistent over-current issue with the right headlight on a 2014 JK. I replaced the OEM headlights almost immediately with the infinitely better Cibie 82440/. Initially I used the KC HiLiTES (6307) H13 to H4 Headlight Conversion Cable. The lights have
the Philips 9003 X-tremeVision bulbs in them.

Within a month or so the right (passenger) headlight went out. Initially I thought that the bulb had burned out so I bought a pair of new bulbs, but when I went in to replace I saw that the existing bulb is perfectly fine.
Removing the light bulb and plugging it back in resolves the issue. I have not found any other solution. The issue comes back periodically once every couple of months. I have tried different bulgs in that headlight and the issue always comes back. Since the KC dongles looked to be of a somewhat iffy build I replaced them with Quadratec ones, which in hindsight don't seem to have a much better build. After replacement the issue is still there.

A few months ago I took the Jeep in for some "check engine" lights, and when they ran the diagnostics they saw codes for over-current situation in the right headlight. They spent some time troubleshooting and decided to blame it on the H13 to H4 adapter. I tried to explain to them that I have already changed the dongle AND the bulb and the issue stayed with the headlight, but they said that since this is an after-market part they are not responsible (under the extended warranty).

This is a (somewhat) reasonable position on their part, so I am pondering my next step. I am tempted to swap the dongles between the left and right headlights just to prove them wrong, but that will not stop them from claiming that it is the after-market lights that are the problem. I am loathe to put the crappy OEM headlights back in for a few months (still have them), and I can't put them in when the issue pops up since by removing the bulb I seem to reset the problem.

Any suggestions for trouble-shooting this? I almost feels like some type of a cabling issue, where wiggling the cable during bulb removal resolves some type of a short.

I have a 2014 and the exact same headlight set up and haven't had that issue.
