Aftermarket on Amazon. Alla Lighting H13-SC-Socket (2 per pack)

 

Unless I'm mistaken, not so in every truck. At least on my 2020 it wasn't. Truck has BLIS, but it definitely had incandescents all the way around.
As far as cargo and third brake lights, mine were also incandescent. Yet a 2017 that I had, pretty much optioned the same as this 2020 had LED in that lamp. You never know until you actually look.
I have the Z Flash module in the truck so I wanted to ditch all the incandescents.

 

Fortunately it's easy to check. I'll ammend my statement; check first before ordering. You may not need to purchase some of the aftermarket LEDs.

 

True. Pretty easy, at least in the case of tail lights to peek through the lens and see. For the reverse and rear turn signals, a little more difficult.

 

It's only a couple of 8 or 10mm bolts and the lense cover pops off.

 

8mm to get the assembly out. Had 'em off many times. Then there's 7mm on the back side of the lens to get at the turn signal bulbs on BLIS trucks.

 

So I finally had some time to dive into the flicker tonight, and man am I frustrated...

So a recap, after installing the Hikari bulbs I was getting a flicker on the passenger side, lower bulb, low beam setting. High beams worked fine. So I figured it was a bad connection in the low beam pos (+) pin.

So I start troubleshooting this afternoon. I start trying to narrow down exactly when the flicker happens. After running numerous scenarios, it wound up being the truck side of the lower light, regardless of which bulb it was actually plugged into. With the truck running, I would turn the headlight switch to "on" the bulb would "flicker, flicker, flicker, go out for about a second, turn back on, flicker, flicker, flicker, go out and stay out" cycling the headlight switch would restart the process. Baffled, I decided to call my Ford dealer, as the truck is still under factory warranty. I described the symptoms to the service writer and without hesitation he asked if I had installed LED bulbs. I said that I had installed LED bulbs and he said that I had to run the factory halogen bulbs, as the LED bulbs did not meet the required parameters of the computer.

Now my question, has anyone figured out a way to trick the computer into allowing the LED bulbs? Or figured out some other work around to allow the LED bulbs.

I called a mechanic that is not a dealership and comes highly recommended in my area. I have used him several times and he's awesome but super busy! So unless it's an emergency he usually takes a day or two to get back to you. If he has any ideas I'll report back incase someone else is experiencing something similar.

The truck is a 2019 F350 DRW Lariat w/ 6.7, incase it matters....

Thanks in advance for any insight anyone may have!

 

These solved my flicker problem with the Hikari LED lights. The ones they sent me had plugs that matched the lights and the truck (not what's pictured) so I'd make sure the plugs were compatible.

 

It isn't just your truck.
It isn't just your luck.

I've tested aftermarket LED headlamp prototypes designed for retrofit into a 2019 model originally equipped with halogens, and found the same unilateral behavior that you found on the passenger side low beam setting.

After many trials, the company I was testing for was able to surmount the issue within the product, with no modifications made to the wiring, nor the oem module programming, of the truck.

While I can't disclose the modifications, or the company, I can tell you that it is not necessary to muck with your truck in order to retrofit LEDs without the flickering you are frustrated with.

So I'm posting just let you know to look toward product selection for a solution. Don't pay to have a mechanic try to diagnose something wrong with your truck, because there most likely is nothing wrong with your truck.

The 2019 that I tested behaved the same way with initial prototypes, and stopped behaving that way when the product, not the truck, was changed.

 

I put Hikari in my 2020 less than a week after purchasing it in October 2020. No flicker, no problem in the 11 months I've used them.
Maybe there was a change with either Hikari or Ford between the model years that eliminated this problem?

​​​​​​I had Beamtech in my 2019, didn't go with Hikari until getting a 2020.
I have the old FORScan speadsheet from both a 2017 and a 2019 and line 726-26-02 in the BCM is called "Halogen to LED Headlight Conversion". I'm not sure if this would solve the flicker problem in the 2019 or if this is to be used when someone converts factory halogen to a factory LED setup. But it may be worth looking into for Nubs.
It's hard to recall at this point, but I think I did make that change in one of my previous trucks and the Beamtechs never flickered.

 

It is my understanding that if you want to change ANY bulb in these trucks from incandescent/halogen to LED, you have to use forescan to change that line. I have a 2021 and tried changing rear brake/turn and got butkis. That rule goes back to 2011 as far as I know. Possibly further. So, your going to want to make other changes to the truck, so get the forescan and join the family. You MAY also need that resistor. Maybe someone who has changed that line in forescan can chime in on that.

Good luck, please let us know how it was solved. I want to convert my 2021

 

You absolutely have to make the FORScan change for turn signals if you're not using resistors. If not, it'll hyper flash in the cluster but the light will actually be flashing at the normal speed when viewed from the exterior.

 

I spoke with the mechanic in my previous post. He couldn't remember if there was an "LED" setting in one of the modules that would allow for the replacement of the OEM halogen headlights. He told me the next time he had a 2019 in the shop he would poke around and see what he could find. He did say that he typically uses Putco LEDs in the trucks that he converts and hasn't ever had an issue with the truck "accepting" them. My problem is that they are better than 2X the price of the Hikari (~$220 per pair!) while I don't mind paying for quality, that's a little hard to swallow.

Hikari has agreed to issue a refund for the LEDs that I currently have (so props to their customer service dept.) so I will be sending them back. My trouble is that I do not want to keep wasting time and money on figuring this out. As I'm sure you all know, changing these bulbs is not a 5 minute job anymore. I don't want to be pulling the front end off of my truck weekly to try a different LED that may or may not work.

Does anyone have any suggestions or further insight? and thanks again for all of the responses!

 

I have Beamtech's in my 2018 and also had a flickering issue. They sent me decoders/anti-flicker harnesses and no issues since. Does Hikari not have anything like that?And I can change all 4 of mine in 10-15 minutes without taking anything other than washer fluid tube and air intake scoop out.

 

Yes, Hikari sent me the decoders for $.01 after I contacted them with the same problem. They solved my flicker without any forscan.
