Headlights randomly turn off while driving

[CaptStarboard]

Do we have any ideas on this issue? Taking it into Jeep next week and would like to pre-diagnosis for them!

I also have a 2020 JLU 2.2 Export Diesel. This started happening on a long road trip. Happened first on a lighted freeway, all lights off and was able to pull into a service station and full reboot my taser. A half hour later it happened on a winding mountain road, in the rain with absolutely no light. Talk about pucker factor! Lucky I have my driving lights to an Aux switch and jammed that on as I braked hard!

A few days later on the road trip home, I noticed it looked like I was flashing traffic in front of me. Finally sorted out via filming with my dash cam that I would flash the left high beam, then the right, all lights off and one left low beam, then everything off for 6 seconds (INCLUDING REAR BRAKE LIGHTS!!). I also narrowed it down to when the distance following CRUISE CONTROL is on. Would happen within a few seconds of resuming it.

Having other electrical gremlins as well, so I figure some module or Can Bus routine is failing. (Started with radio volume fade with speed working wrong, then the USB drive music playback started resetting the entire system every 30 seconds, side mirror obstical detection started failing when in 4wd, traction control started tripping itself off while in 4wd). Like I said a fair few gremlins are starting to accumulate so want Jeep to deal with it while in warranty!

Thanks CaptStarboard

So mine WAS the JL Taser mini....

So mine WAS the Taser JL mini.... Once I pulled it out and updated the software that issue of full shut down went away. BUT it now flashes the high beams and turn signals instead. That I can live with (and LIVE!)

At 5,200,000 miles it’s not surprising to have a few issues here and there

I have had several issues where my headlights turn off. I have to twist the knob on and off a few times untill they come on. Happens if switch is in auto or using it manually. Most times it happens once and I'm good, but last couple of days it's been more often. I plan on taking it in to dealership, but I work out of it and it will be a couple of weeks.
Any ideas?

I have a ‘23 2 door stock Sport-nothing done except changed headlights to LED. 14,000 miles. I do very little night time driving, but I notice the lights go off, and then come back on. I pulled over to check them and see if I was crazy and headlights were just off, but rear lights still on. I only use Auto mode. Obviously I need to take it in and would love to have any education I can get beforehand. Thank you for any comments.

You changed the headlights yourself? To what lights? Did you update the software to reflect the LED headlights?

No-I am 74 and, well no. I have had several wranglers and I use a specialty place. They put different lights in my ‘19 Rubi with no issues. I had them installed well over a year ago. So-good question!!!!!
