 Are you Looking to change your headlights and grille on your custom Silverado to the LED HID / signature curtain daytime running lights that High Country’s come with and the bow tie grille ?


 

Here’s how I did this to my Custom Trailboss ... how to video.  Videos nothing special but it’ll give you the pics with notes /video clips that  I took so you can convert yours over if your wanting to .  Back when I did this conversion I couldn’t find anything online that really shows how you do this so hopefully this helps the next person do this .  Takes about 3-4 hours 

 

 

cost is about $3k for all new oem parts .  I got my headlights , wire harness through Gen5DIY.com  $2400 and the bow tie grille $580 through gm parts warehouse.   Both are great companies I’d fully recommend that made the process really easy .
 

  I’ll list the part numbers too if you wanna research and look for some lower prices if wanna go with used parts or shop around if you wanna that route but don’t forget you’ll still need the headlight harness which is about $250 from Gen5DIY to make all the lights work properly .  After you sell your used Custom headlights and grille parts from the conversion you can get back about 1k dropping the cost involved about 2k with new parts.

 

May ask why not just buy the LT trail boss ., well here’s why I did not .. when I researched this is what I found ., 

 

  My Red Custom trail boss came with the halogen lights and the LT Trailboss has the better looking lights that are LED  (not too bright though but have a good look to them still) but they are not HID LED which are way brighter unless you buy the midnight black edition trail boss or the high country which #1 I wanted the red trail boss not black , # 2 I wanted HID LED lights not just the LED lights , so I made my own custom set up for a small cost compared to getting a midnight edition Trailboss or high country

I used the same headlights but I bought em on ebay as low mileage takeoffs. 1200.00 a pair, the grille is the gloss black oem but from ebay too for 400.

 

Then sold the old lights 350 each and the grille for 300.  So my swap was 1k plus the harness.

Has anyone done this on a 2021 custom trail boss model yet? When you go to gmparts warehouse for the grille it says that it does not fit the vehicle and suggests a different one. Would I be fine going with the one you suggested?

It’s my understanding that the new headlights necessitates the new non custom grill so lt,rst,ltz,high country grill.

Hello All,

I'm sure everyone that converted had a straightforward and issue-less conversion... but hopefully someone has some insight:

 

Have any of you seen an issue with the DRLs blinking 3 or 4 times and then shutting off completely? If not would you have an idea of what could be causing the issue? All other lights work perfectly, its just the DRLs that are disagreeing with this mod. I posted this in the Troubleshooting forum, but hoping someone here may have some ideas. This is on a 2022 Custom Trailboss LTD (same as 2021) I have a video of what I am seeing below.  Any help is greatly appreciated.

Have a 2019 trailboss with halogens and im looking to switch to basic LEDs. My question is if i buy the WHOLE assembly is it just simple as plug n play or do i need a conversion kit on top of buying the WHOLE assembly? Thanks in advance

If you swap to the OEM LED housings from the halogen ones, you will need to swap the grille to an LT\LT Trailboss\ RST\etc. grille. you will also need to buy a harness for the headlights to work. Gen5DIY sells one.

do the oem led headlights light up the road better , are you satisfied with the light output. the reason i ask is because i am looking at a 2021 silverado rst with led headlights and just wondering are they really good

The RST/LT/LTZ headlights are not the same as the ones that I have, which are the High Country lights. The High Country lights use a ballast/LED control module. The output on the HC lights is pretty good and they are brighter than the RST/LT/LTZ. The only caveat that I see with them is the beam pattern is not wide enough. That will be the same for all of the OEM LEDs though. I can't say for sure how good the non HC headlights are, but people in this forum have expressed that they wish they were brighter. I don't have that problem with the HC lights.

My Chevrolet Silverado has recently returned from a car service, so I have not had time to change anything in the cabin yet. I need to buy LED headlights for indoor lighting. I have seen several suitable options, but I found the best one here https://www.amazon.com/car-lights-car-led-lights/dp/B09L86JRRM. I often go on night trips, so I want to spend this time in a pleasant atmosphere. As far as I understand, there is a built-in Vont Car Strip Light microphone synchronized with the music in the car. Now I'm even happier that this thing will soon be mine.

I know this thread is old as hell, but wondering if this still works on the 2024 Custom Trail Boss? Do I need to source a different set of headlights and grille? Or is it still the same?

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
