Didn't get tot test the turn signals this weekend as I was busy and needed my truck so I had to put it back together. However, I installed some capacitors between the low beam/ground wire before reassembly and the headlights function just fine with the truck running. I tested them Fri & Sat night and not a single issue so far. So it appears for those willing with an SLT only a repin & capacitor is needed for the lights to work like the 14-15 slt lights. Now if I can only get those DRL's to go off when turn signal is applied.

Exactly, headlights would cutoff because they go on safe mode to protect the LEDs from the pulsating current and not because of BCM, canbus or any of that. Im glad it worked out for you. And for non SLT just add a NC/NO Relay. The relay switches the current from low beam to DRL and switches it back to low beam when need it thats all needed. Edited by Dbeto54

Sorry I'm a little late, I've been in the Caribbean for a little over a week and just getting around to posting pictures. I know there was a lot of fuss of whether or not the SLT lights would so I bit

Well, I finally got around to installing my 16-17 LED headlights. A huge thanks goes out to @zmnypit for fabricating the adapter harnesses.

One more night pic that should help.

zm,

 

Could this be made to work on an SLE model? Do the SLT harnesses have additional wiring for the LED DRL,s?

Dbeto's silverado conversion basically went NON-LED headlights to 2016 LED DRL headlights with only repin correct?

I believe he added a NC/NO Relay. The relay switches the current from low beam to DRL.

This is how I did the relay

Low Beam + coming from harness to COM, NC to DRL, NO to Low Beam, and one of the coil to + from parking lights and the other to chassis ground. You can use one on each headlight or just hook up both left and right Low beam to NO and both DRL to NC. Thats how I did it with just one.

Dbeto....Thanks for the schematic. looks pretty straight forward to me now. :cheers:

Not a problem man. Thats what the forum should be for, to share info and help each other out on DIY projects and on whatever we can. Edited by Dbeto54

So you are controlling the coil on the relay with power from the parking lamps as opposed to the turn signal wire and it still energizes the coil and opens the drl circuit when using the turn signal?

Yes the coil is only energized on auto lights at night or if I do it manually by turning the light knob right. Otherwise the relay is Normally Close sending the current to DRL all the time. What I did was just reroute the low beam drl current to the led strip and back to low beam when coil is energize. The turn signal function is done by the headlight module it self. The drl wire is still hot while turn signal is applied but the module cuts off the led. I believe sierras is done by the bcm instead of the headlight module. I dont see any other explanation for it not to turn off.

Any more movement on this?

Just that the SLTs work with a repin but no DRL shutoff with turnsignal applied. I've been running wide open the past couple weeks so haven't had much time to sit and tinker with it.

You cant put on GMC headlights on Silverado's, the fenders are not the same, but we can upgrade the 2014-15 Silverado's to there new LED headlight.

It can if you want to swap some front end parts. Look at user Dbeto54 threads. He swapped the fronted including headlights.

Yeah I saw that... but I want it like the Sierra, just head light swap haha! It looks really clean though!

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.
