Factory Halogen to OEM LED Headlights Swap - What I Learned

[jbcrane]

To be fair, that $1000 doesn't just upgrade the headlights and foglights from halogen to LED. He got the original "factory option" version of the LED Headlamps (withLED bulbs, and its unique headlight assembly that includes the halo daytime running lights) and his VIN is registered as having those LED options as dealer-installed.

For my 2021 Wrangler JLUR, I went to Amazon and purchased the list of LED bulbs suggested by robinja. I installed them in my Wrangler, and everything worked just fine out of the box. I did not have to have the dealer or a Tazer JL Mini input the code which tells my Jeep that I switched to LED bulbs. But let's be honest, I don't have the halo daytime running lights, and my VIN still shows that I have the stock halogen bulbs. The upside here is that I only forked out about $100 to Amazon.

In the end, what direction you choose can be a combination of what you know (originally, I managed to falsely convince myself I had to install a whole new headlamp assembly to get the LED lights), what parts you want to use (Mopar, third party), what your ultimate goal is (I like the Halo DLR, and I like having my VIN showing LED lamps as dealer installed, but neither one was a must-have), and how much you're willing to pay for those things (I was unwilling to pay a premium for either).

$1,000 wasn't a wrong choice for a headlight and fog light LED upgrade. I think he got much better results than I did for $100. That $900 different may or may not be worth it to you. And in the middle, you're going to find all sorts of third party LED headlight assemblies with different layouts that look quite cool.

Couldn’t have said it better. I’d planned on the cost when I was building it on-line, so was already prepared to spend the money. Yes, there are less expensive solutions. But for better or worse I’m a “do it once and do it right” (or better put, the way you really want to do it) then get on with life. No regrets, and not that I’ll ever sell this Jeep, but the completist in me can rest knowing that it’s now how I’d have ordered him from the factory.

I did the same as you - and it was very easy - purchased a 2021 Sport S and bought my LED headlights from Athens Dodge (amazing for online OEM parts) and did the swap...

Which Athens? GA, AL, TX, elsewhere? I've found CDJR dealers in each state with a city so named.

I ask because I had a similar and great source of OEM parts from an out-of-state Honda dealer.

I need help. I am in the midst of doing this swap on my 2019 wrangler sport. I have the fourth wire installed but I extended the wire instead of going through the firewall so I cut the ends off and soldered on more wire. I have factory led fog lights installed but no led turn signals. What exact code to I need flashed to have the halos, brights, and fogs working but not have an error code on my turn signal. Please help

I believe it’s code LPX. Here are the install instructions.

Most difficult part for me was hanging upside down in the front passenger seat trying to gain access to the wiring block so I could add the wire to the correct pin. I “think” I connected it correctly, but since I had the dealer add the code and test the halos, they may have double checked my wiring work, lol.

After having spent the last month+ working through the rather confusing topic of swapping my stock halogens for the Mopar LED and Fog Light Group, the issue was finally resolved today with a second trip to my (great) dealer. I think I've read through every thread I could find on the topic on this forum and others, and even reached out personally to a few individuals for clarification. My hope is only that this information will help someone coming after me who may face the same issues/questions.

I have a '21 Sport S Unlimited and the LED group was the one thing this guy didn't have that I planned to swap out from the beginning. I know there are other after market lighting solutions out there, but for better or worse I'm an OEM kind of guy and the lights had to be the production LED head lamps. I also bought an extended warranty when I purchased the vehicle and am up front with my dealer with any questions or concerns regarding warranty.

I purchased the Mopar LED Headlight kit (part number: 82215136AE) from BAM at a price of $749.25, free shipping UPS ground, and the LED fog lamp kit for another $224 plus $8 shipping USPS. The headlights arrived in a large box containing two individual boxes, each with one head lamp 'suspended' between two plastic sheets to avoid impact damage. They were very well packed, even against UPS' rather unkind treatment of packages. The LED Fog lamps were packed well enough in a smaller box and sent in the mail with no damage.

After receiving the lights I did a little research and determined that even someone like me (not a mechanic, but I do the best I can) could probably put them in. Before doing so, though, I made a trip to my dealer with the Mopar part number and my VIN number and had them double check they would work. Confirming they would, I then asked if installing them myself would damage my warranty. "No, as long as they are installed properly," was the reply. Installing the LED headlamps was easy. The many-page instructions were clear - most pages pertaining to the additional wire harness running to the BCM - WHICH YOU DO NOT NEED WITH A '21 VEHICLE. So you remove the front grill assembly, unbolt three bolts holding each halogen lamp assembly in, unplug the harness, fasten the same connector to the LED plug then bolt the new LED assemblies in. Super easy. The fog lights were actually more difficult than the head lamps because of the Sport's front pieces between the fender and bumper, and the fasteners used to hold them in place (but that's another topic)

Once everything was installed I turned on the Jeep and things seemed to be working. Fog lamps produced light, headlamps produced light on low-beams, but high-beams there was a sharp cut-off at the bottom half of the illuminated field - the road in front is completely dark, but the horizon is illuminated. Clearly not right. Off to the dealer we go for the planned flash.

There are two codes the dealer needs to add to your VIN as a "dealer installed option" through their software: LPX for the LED headlamps, and LNV for the LED Fog Lamps. During the first dealer flash - for whatever reason only the LNV code for fog lights was added. When I got the Jeep back there were still no halos, and my high beams were behaving exactly the same as they had before: strong illumination at top of range, complete darkness on bottom. So a second trip to the dealer revealed the problem: for what ever reason the LPX code for the headlamps had not been entered. Once this code was entered, along with LNV for fog lamps, everything worked perfectly. Halos, high-beams, fog lamps, everything. It's a beautiful sight.

There is a third code, LPY that enables the Halo lamps, but is intended for LED side marker lights too and causes problems with the non-LED side marker package that comes standard on my Sport S. When they add this code the blinker indicators on the dash freak out. Removing the code fixed the issue. The dealer flash cost $138 ($120 plus $18 shop fee), bringing my LED package total to $1,119.25 - actually just below the $1,145 currently listed on the Jeep web site build ap.

Was it worth it? Without a doubt, heck yeh - absolutely. There's a significant difference between halogen and LED. I do a lot of highway driving, often times at night. Especially in the mountains, and throughout the West and Midwest, deer on the road are the single biggest reason for me to throw as much light ahead as possible, and the main reason for the swap. I believe that anything that can be done should be done to reduce the chances of hitting deer on the road. Not just for you and your's sake, but the deer's sake too.

My dealer (Fort Collins Jeep) was and is great to work with. Yes, it took two trips to get it right. But it's not a super common thing yet and they were figuring it out too. They were super accommodating, helpful and easy to work with. I couldn't be happier with them, my lights or my Wrangler. There was of course no charge for the second trip to reflash.

One more thing about JSCAN, TAZRS, etc. I read a lot about others taking this approach. If the dealer flash didn't work for some reason it was perhaps a backup plan. But in keeping with the OEM/Dealer/Warranty-honoring ethos, my strong desire was to keep the whole project with nothing to hide, no questions and within bounds, so to speak.

So for anyone else out there who finds this thread because they are thinking of doing the same thing, hopefully this will help clear up confusion. Much depends on the year of your Wrangler, and (I think) to a lesser extent the trim level. My '21 Sport S has the 4th wire running to the plug from the harness so I hoped it would work. It did, and I did not need to install the extra harness provided in the kit. This is my first Jeep and I've already done more on it in the first 4 months of ownership than any other car in my many years. So tearing my fender off and plugging wires into the control module was just a little out of my comfort zone. I know some of you guys can do it with your eyes closed. Not me....

Hope this helps.
Peace, JBC

I'm so glad to see your post.
Looking for a used JLU. Few here have the LED headlamps.
This may be a good fix for me.

I just picked up a set of second-hand OEM LED Headlights. Based upon what I was reading with some of the 2021 folks, I wouldn't need to run the extra wiring harness from the headlights to the BCM. When we tested to make sure the lights would work, I noticed that the plug going into the back of my headlamps only had three wires. I have a 2022 JLURD. I was somewhat shocked. Now I'm just debating on going the Tazer route or Dealer Flash. Plus I need to pick up that wiring harness now.

I have a 2021 JLUR and I have 4 wires to the drivers side and 3 to the passenger side. So, my driver Halo works and my passenger doesn't. Go figure. I guess I have to run a jumper across to tie them together.

 

[swang]

Was planning to upgrade to the Mopar LED headlights and thought it’d be a no brainer with my 2021 JLUR, but seems like there are some inconsistencies with that 4th wire in the wiring harness… I can just disconnect the stock headlights and check the connectors, correct?

 

[sailscall]

Pull the grill and then the headlights. My 2021 sport with a Jan 2021 build date had 4 wires on each side. I opted for the Oracle Oculus BiLED switchbacks. I like when the amber halo blinks in conjunction with the turn signal.

 

[ryandrews83]

I just completed the Halogen to LED swap on my ‘21 JLUR this weekend - headlights and DRLs.

Having the 4th wire on the 2021 wiring harness made the headlight install super simple. DRLs were a different matter. Took forever. Broke all but two clips removing the fenders, pain in the ass to replace. Couldn’t get a couple of the 10mm bolts holding the fender on back in, so running without them.

Tazer was simple enough. Halos, headlights, DRLs and turn signals all working well.

Really happy with the results.

 

[znakos]

I had standard halogens on my 2020 Sport S and did the upgrade to the LEDs with a dealer flash, and they worked great. I'm about to trade the car in and want to go back to stock and sell the LEDs.

Can someone confirm if reverting back from LED to halogens, will this require another flash to not trip some sort of CEL?

Thanks in advance.

Im installing OEM LEDs next week on my 18 JL. I’m having my body shop put them in but they are unsure how to do the scanning so I am doing that at the dealer. Is there any risk in plugging in the fog, DRLs and headlamps before getting everything flashed and upgraded? Could I potentially fry the lights, or would they just not function properly without the flash.

debating whether or not to have the shop plug in the lights or just to have the lights unplugged until I get them to a dealer.

thanks

I’ve got a question regarding Halogen to LED turn signal/DRL swap. I bought a set of painter Rubicon fenders that came with LED DRLs…currentl still have halogen head lights. LED DRL’s work, but turn signals do not. Brought it to the dealer and they flashed it, but it didn’t take, still no front turn signals, and get error messages and hyperflash. If I decide to go back to my halogens, do I need to have the dealer remove the code they added, and if I decide to go the “JScan” route, do I also need the dealer to “undo” what they did?
another question I have, is is it possible I’m getting the error messages because the jeeps looking for the halos which are not there (as I still have halogen headlights)?

You are getting the error message because the LED in the fenders pulls less amps than a halogen would and it thinks you have a bulb out because of the lower amps. I just swapped from sport fenders to Rubicon with LED on my 19 JLU. Sounds like your Jeep still thinks you have halogens. without the proper program my guess is the DRL is acting as your marker/turn signal and believes it is out because of the minor amp draw compared to the halogen amps it should be seeing. I have JScan and programmed my fenders with that app. Check out this thread and it explains everything.
