Has anyone who has installed LED take-offs resolved the high beam not working and halos not working issue? I also get a occasional flicker. Mine are currently installed on a Sahara with the 3-wire configuration going to the headlight. With there being this many issues I would assume there is special wiring harness that needs added.

I thought the Sahara harness supported the LED headlamps with Halos and it was a plug and play but I also think it takes a dealer flash to get it all working correctly

I have the same exact issues - Sahara with 3 wire harness. Also issues with hi and low when in hi. Halos not working either

I think what you will find is that takeoffs are not just plug-n-play.

The OEM lights use 4-wire harnesses. The extra wire most likely powers the Halo. Reference: https://www.jlwranglerforums.com/forum/threads/18-jl-sport-and-mopar-led-upgrade.7284/page-4

The question then becomes how to get this resolved. I’m guessing: Purchase two new LED harnesses (one for each light), and solve how to wire them to the main box. It shouldn’t be that hard, but it will be a day job.

I don’t know how Jeep is going to solve this issue with the LED lights when they are available for purchase. I’m curious to see how they will power the ring without some external adapter that taps into some nearby power source.

My 2 cents.

I honestly like the idea of having halo LEDS but I’m not going to jump thru hoops to get them to work correctly like splicing into existing harnesses so I’m guessing I will wait for someone like Diode Dynamics or similar to come up with a simple answer to use my existing harness and if not I will pass on halos and just get LED lamps

I don’t know if this will help but here’s the wiring diagram

Order the OEM wiring harness provided with jeeps equipped with factory LED headlights.

This wiring harness issue really makes me want to wait until Mopar releases their own kit before I splurge on some OEM LED headlights takeoffs.

I’m still waiting on this I’ve had my takeoffs for a while now and just haven’t been using high beams. I don’t think a dealer flash will have anything to do with it. They will most likely have a adapter/harness that has a capacitor to control flicker and turns on the halos with the headlights. I’d really like them to make the halos come on with the running lights but I don’t see how they could make them plug and play that way.

I have done the same as you I purchased the Mopar led and had someone install I even had dealer flash most of the time it works but do you get occasional flicker of the light and it even go off?

I just talked to my local dealer and the harnesses are the same at the headlight assembly, they differ back against the firewall. The parts tech said that it is not something he would recommend doing. He did say Mopar sells a 6 pin pigtail harness that can be used if desired.

Are most people having issues of flickering with putting LED take offs on their halogen Jeeps?

He might be misinformed. The Halogen JLs come with a 3 pinned harness at the light and the LEDs have a 4 pins. To my understanding there’s nothing Jeep has released that would allow halogen models to upgrade to the OEM LEDs yet.
