Baking them can cause issues. Some of the plastic inside warps.

Those are sweet!

Have you baked them before? What sort of issues? More so than the 14/15 lights?

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.

Hello guys I have 2015 SLE and I bought the 2014/2015 Sierra NON SLT to 2016-2017 1/2 Ton SLT LED Headlight Harness from Gen5diy everything is working fine the only issue I faced is if I just want to turn on the "C" I cant it comes on with the whole headlight it doesn't work alone, the DRL works fine during the day but lets say at night I just want to turn on the "C" without the Headlights I cant, is there another harness! I talked to Jarod he said this how its designed!

Jarod is right, the DRL is just that, a Daytime Running Lamp. You can't run them at night without the headlight.

Man, I should have waited to buy my fogs. Would have been nice to save $50.

Im considering doing exactly this. Is it annoying to you that way? I'm curious, otherwise was it plug n play with the Gen5diy harness? (Part #)?

Yes I have, and these were done by Fastheadlights with one off Diode Dynamics C-shape switchbacks. Its not as easy as with 14-15 lights, and the lenses can flex rather easily causing lens distortions.

Yeah DRL works well during daytime its bright, but what I know if you want to turn it on you can without turning on headlights and the "c" turns on dim. Like the original 2016 they have 3 selections 1-DRL 2- "C" on with the headlights 3- "C" only

Are you talking about the internal lens for the C warping due to heat?

You have 4 options

 

off - auto - park - on

 

Off - All lights off including DRL

Auto - C is on as DRL at full brightness during day while truck in drive, headlights turn on automatically with sensor, when the headlights turn on the C will dim.

Park - C is on as park lamp dimmed, side clearance light is on headlights are off.

On - C is on and dimmed clearance light is on headlights are on.

 

There is no way not even on 2016 to turn just the C on at full brightness with the factory wiring and controls. A custom wiring job and separate switch would be required. I' not familiar with the wiring harness for the 2015 SLE but it originally didn't have DRL LED's so it likely doesn't have a separate DRL wire as the DRL function was integrated in the headlight itself. I'm not sure the method Gen5 used to get around this to activate the DRL during the day without turning on the headlight bulbs. Did you install the harnesses yourself and did they require additional wiring beyond just being plug and play?

Off topic, Any progress on DRL shutoff?

Yes.....the bezel that holds the factor c-shape led lens....its like a thinner shroud

 

You can also get hairline fractures on the inside of the clear lense when pulling them apart.

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
