Pictures of my 6.2L AT4 on stock suspension with 36inch tires, Borla Exhaust and Amber DRLs

Thank you!!!!!! Looks like I have something to do this weekend. I did remove the bracket so looks like I just have trimming to do.

Looks good, reminds me of a bigger 2024 canyon at4. Where did you get the wheels? They look like OEM. Put me down as interested in the daytime running lamp mod if you do ever want to sell them.

It was really smoky in those yellowish pictures.

Good looking setup. Amber DRL's very unique and set's it apart. Can you share the parts used/links and a write up on making this. Wouldn't mind taking a stab at this.

I guess ya, if there's enough interest. I can manually make these, bu they are time consuming and parts are expensive. especially the PCBs.

They are cheaper to make in larger quantities, and instead of locally, they will be 1/4 of the cost if they are made in China.

I'm making two of these for my buddies but they're eating up the cost and labour.

Very impressed! I think there would be a pretty decent interest in these. I have a Refresh LT Trail Boss and would be very interested in this mod (I thought the Global B architecture would make this impossible) and it should function the same as the Sierras.

I'm really loving the amber lights. I think a plug and play harness would be a big seller.

Good business opportunity for the plug n play module. If it's something you want to tackle! A lot of stress involved.

Fair pricing can be tricky for both the builder to cover time, and parts for development, and customer.

Not opening up headlights: Win

Not having to deal with sealing headlights again: Win

Not having to send them somewhere and have weeks of downtime: Win

Not voiding warranty: Win

Still using OEM lighting: Win

I bet with some additional programming (maybe?) you could get the turn signals to be sequential.

I wonder if something like that would be applicable to the refreshed Silverado DRL lights?

Looks good! What wheels? What is offset? What size tires?

Would you be able to make me one or share exactly what you did?

I would be interested in the Amber drl as well

Zazu62 · January 10

Are you going to offer the amber drl kit for sale? I would be interested

So… 37x12.50 tires on 18’s is out of the question right? 2019 AT4

I saw that these trucks had full amber lights and wanted to use those as DRLs. I looked online and found only few options:

One was to bake the headlights in the oven and take them apart and replace the white DRL Led strip with yellow one. This is too much work and chances of getting it right are pretty slim. For me at least. Not to mention no more warranty on headlights.

Other option was to replace it with aftermarket headlights, but those are all junk and look very cheap with very dim dotted DRL LEDs.

I opted to design my own little circuit board that controls the function of these DRLs.

The circuit board I made is very small and compact, about 4x4in. The weatherproof case is about 6x6in. And for it to work you just unplug the harness from the headlight and plug this in between and you get amber DRLs which you can change with a switch in the cab.

It was a lot of trial and error and spent a good amount of money on versions of different PCBs that had to be printed and after a few revisions I got it working. And the OEM harness plugs were hard to find initially but lucked out and found em online.

I made it plug and play, because I didn't want to hack or modify any harnesses or headlights and maintain the warranty on those items. GM is notorious for voiding warranty for stupid ******. This way I can just pop these modules out before I bring it for a service.

What the PCB does is, when its on, the DRL signal to white LED stops and in its place the amber LEDs light up. The hard part with designing the circuit was retaining the turn signal and hazard lights functionality along with the amber DRLs. And making it all work with the turn signal feedback loop.

When the PCB is off, then it acts as a pass through, like its not even there. Then everything works in factory mode as GM intended.

Is there any way you could show some pictures or maybe even a diagram so I can try and replicate this on my AT4X

What year is your HD? Should be a pretty simple hack. I’ll go through it this week and update everyone that is looking to do the amber drl. I went from 2021 to 2024 Front end on my 2500 still in the process not quite done yet lol
