XLT to Lariat Headlamp Upgrade

[Deleted member 1634]

The lighting difference is huge!!!

I was trying to aim my new lights,and we were going to use a buddies truck as reference.I had him turn his lights on parked beside mine,then turned mine on,and it completely washed his out.
He was even blown away by the difference in light output.

Did he have just the stock halogen bulbs though? Or did he have the upgraded LED bulbs in the reflector housing? Because there's no doubt the stock halogen bulbs are pathetic.

I think the question really comes down to whether a set of Lariat (or other not yet available projector housings) are better, or worth it, than just getting a set of LED bulbs for the XL/XLT reflector housings.

I still have the reflector housings in my truck and a while back I installed the led bulbs in it. Yes it was definitely brighter but now that I'm doing more offroad driving including at night is seems like I can do better with the Lariat headlights since they use a projector housing. If there is a lariat at my dealership im going to do a check to see how it compares.

Gotta ask the dumb question......

‘Lights are in and look great!!!

‘’When I go to use FORScan and write,it stops and says peramiters not met and stops.Am I missing something obvious or did I forget a step.
Nevr used it before so trying to learn without completely screwing things up....

Any knowledge is deeply appreciated.

I truly need the baby steps guidance/version on how to.

If someone wants to pm instead of bore everyone else that is familiar,that would be great as well

Thanks!!!!!!!!

Hey Gary, did you get the help you need here? I've just completed the FORscan mods and I can give you some videos and pointers from what I learned from Carl.

 

[RamblinnMann]

I have not yet,and any steps,tips guidance etc,would be hugely appreciated for sure.
Shoot me the vids knowledge etc.

Thank you Carl!!!

This video is what I used to get started with registering FORscan and how to connect to the vehicle and everything Getting Started with FORscan

Here's the adapter that I bought to connect to the truck.

Here's the link for ELM327 Drivers that you'll need to install on your computer in order to connect the adapter to your computer properly. You can also buy their adapter, but if you don't no problem you'll just want to make sure that all the driver packs are installed based on the computer operating system you're using.

When you connect the truck, put the ignition in position 2, right before the 'engine on' position 3.

Follow Carl's codes on Post #121 and hit 'write all' once you've input the changes in all 3 rows at the bottom. Don't forget to save the factory code first though! Follow the video above to do that.

Last, once you've made the change, and cycled the ignition, it may not look like it's worked. To check that it's worked, put your lights in the auto position on the dial, make sure that daytime running light has been enabled on the dash screen (it's in the vehicle settings menu --> lighting I believe), put your ebrake on, and put the truck in neutral.

When you go and check the lights you should see the LED strip on with no headlights or tail lights on and you're done!!

Let me know if you've got any more questions.

Thanks for the reply,and the tips.

My question is,do you have to change the other settings in the BCM for all under DRLS’s also?

Nad I am still confused as to the 0 or 1 0r 2 thing with relation to if you have halogen or led? Ehat does that mean?Does it refer to if you have halogens stock and need to enter the value for that,or your going to LED or?

Hey Gary,

Sorry for the late reply. Those are the only three things that I changed and as far as I understand what others did as well. Everything else just leave the same!

Like you said, the 0, 1, or 2 value basically refers to what came stock on your truck, so that's why it needs to be changed as well so that the computer knows that there's a different type of light in there.

So, I replaced the stock headlight and fog light bulbs with LEDs on my 2020 XLT -- do I need to go into Forscan and change something?? The lights seem to work fine ....

If you only replaced the bulbs then you do not. If you replaced the entire assembly then yes

Great! Thanks, Frenchy!!

Well I finished the swap. Shout out to @earsmccoy for the video and making it look too easy. Ha ha. My advice is just take off the skid plate then the two end valence bolts are easy. The forscan settings in post 121 work great. Thanks all for sharing the wealth of knowledge.

Finally got around to changing the settings and for me my error was trying to write them all at once.

Kept failing,and would not finish.

Once I figured out that I needed to write them one at a time,it worked.Don’t know if that’s the normal way,as in you have to write each line one at a time or not.But,that’s what worked for me.

Thanks again for the assist!!

I believe you can make multiple changes to a module and do a "write all". Otherwise you need to write each change if you use the write button up by the change. You should then do a "save all" to back up your changes. Give it a new name so you don't overwrite you last save that worked.

Got mine installed today! Bought two used ones on eBay for $700. That install was a PITA

 

[Frenchy]

As much as I would love to do this to my truck I want to find someone with these so I can compare. Its nice to see difference in person.

 

[Frenchy]

It is truly a big improvement.Really surprised any manufacture still uses a halogen bulb lamp anymore,especially when even brands like Kia etc have better lights..

Driving at night is a drastic improvement over stock,I am soooooooo glad I did it to my XL.

At the moment I already have led bulbs in place of the halogen buldbs but i have the feeling the Factory led woyld be much better.

Great vid. I can’t believe you have to do all that just to switch out a freakin headlight.

Has anyone that has done the swap had issues with turn signals? When my light switch is in auto and I put the turn signal on, the speed of the flashing light seems to randomly increase and decrease. Almost as if a bulb is burned out. If I'm just sitting at a light it will be fine but if I'm braking or accelerating the faster flashing pops up randomly. It doesn't seem to happen if my light switch is off or on the manual "on" position, only auto. I did the adjustments in FORSCAN that are detailed in this thread for the LED swap.
