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.

I took some pictures of my truck few days ago, thought I'd share.   Tires are on 22inch rims and they're around 35.8inchs when measured using a measuring tape.   Borla S-type exhau

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.

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?

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

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

      Oil Consumption

      By Chuck FB · Posted

      So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !.

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.

      It costs $5,250 for the Yukon Nightfall option (black wheels, emblems and illuminated black GMC grill badge). What a "deal".

      I keep getting the above error message on my 25 Sierra.  If I reset the infotainment unit (via the phone hang up button) it will work again for a day or 2.   But I dont want to do have to reset  all the time. Works fine in my 2023 Corvette. On both vehicles I connect wirelessly.   I have a Google Pixel 10 Pro XL, phone is up to date.  Any Ideas.  See attached
