Are the caps on the Sierra headlights necessary at all?

You don't need them to make them fit, you do need them to help the bulb function properly with its cooling blades/fan whatever the tech word is for that portion of the bulb is. I'd recommend them without a doubt, it's still a little tight in there even with the extended caps. With the extended caps you can put all your parts inside the cap itself instead of mounting them on the outside. But, the Jury is still out on if putting everything inside the cap is going to be good or bad yet lol.

Oh My God, These Vleds are expensive. I'm happy with these 2k Lumens 20w 9006 I got from ebay.

Any pics of the output?

 

The LMZ's are rated to last 30,000 hours. If that holds true, I'd say the price of the bulbs would be less than the total you'd spend replacing the OEM bulbs over that same span of time.

Damn!! Did u have to send the bad bulb in? Any idea what the issue was/is? Looks like you have a Silvy from your pic (I'm on tapatalk right now), did it fit in there without needing a modified dust cap?

No, you don't have to send them in. I noticed when I turned the fog lights on that the bulb was glowing blue, almost like a halo effect. I shut them off and turned them back on. However, that bulb never came back on.

On another note, I'm going to try to stop by and talk to my buddy at the dealership tomorrow to get the BCM flash and new bulbs in from the TSB set up. Can't wait to see what these do with the new update.

Hopefully it was just a bad bulb man. I've been paranoid as is right now about leaving the ballasts inside the assembly, and I know mike1220 has been even more so than I haha. Just trying to figure out what may have caused it if it wasn't just a $125 dud.

It's a TSB that was released on 2-27-15 (I think), it's supposed to address the poor OEM headlight output. Involves flashing/updating the BCM to give more voltage to the lights as well as a new upgraded bulb made by a company called Volsa. The TSB number is PIT5374 if you want to call a dealer to ask about it.

 

This thread has all the info you need on it, first 400 posts or so are useless, the last 50 or so have the meat and potatoes.

Yes I've still got the LMZs in, I plan to take them out before I go in for the update. I'm just guessing, but if the extra voltage the update sends to the lights makes them brighter, I'd say it would help these as well. I don't know the tech specs on the LMZs or if there is a certain voltage that can harm them, but I'd say it couldn't do anything but help them.

 

Anyone here have LMZs installed with a truck built AFTER the dates listed below? Trucks built before those dates are eligible for the TSB, ones built after already have the update.

 

Here's the run down of trucks eligible for it:

 

Here is the wording of the TSB for applicable build dates:

 

  • For vehicles built before 12/23/14 at Flint Assembly (11th Vin Digit "F"), 1/13/15 at Silao Assembly (11th Vin Digit "G") or 1/16/15 at Ft. Wayne Assembly (11th Vin Digit "Z"), reprogram the BCM with the latest calibration available in TIS2WEB starting on 1/12/2015. The new BCM calibration will increase the voltage to the headlight bulbs in both the low beam and high beam selections.

     

    Important: All vehicles built after the above dates already have the new BCM calibrations and the BCM reprogramming does NOT need to be performed.

Let us know how it goes and be sure to take some before and after pics. Would be nice if you had a meter like Spurshot does so we could see for sure if there are any actual improvements in light output.

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      By Black02Silverado · Posted

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
