Been watching this topic and glad there has been improvement in light performance. I called my dealer today and he was unaware of the bulletin, but was very willing to look it up and get bulbs on order. Will see how this goes from here......

 

 

Is it possible to get the fog lights to come on with the low beams? Instead of pushing the button every time...

yes there is a tread for the fog lights on with low beams.

Had mine done today and I csn see the bulbs are brighter but they are aligned horribly

You may have to make sure the bulbs are seated correctly. Mine had a dark spot between the head lights the drivers side bulb was not seated right.

In regards to fogs matching the headlights, it won't even be a close match. LED Cree are around 6000-6500K and the Vosla halogen are 4000-4300K.

Ditto, several pages back I have a picture that shows a dead spot, my pass light wasn't in correctly

So the vosla's match the led running lights!!! Awesome!!!

I think he was looking to match fogs to the new headlight's color.

Correct these bulbs are for the fogs to match headlights

Well I finally got to drive mine on dry roads last night. I had been using the modified 9012 bulbs, now I am on the updated BCM programming and the new VOLSA 9011 bulb.

 

From what I can tell they new setup is as bright as the 9012 bulb and is about equal. The one noticeable change is the new VOLSA bulb is a whiter light than the 9012 bulb so that is a plus.

 

I am pretty happy with the improvement, I also had to lower my headlights down a bit from where I had them, so now my high beam aim is better as well. I actually got brighted the other night by an oncoming car where before if I flashed someone they never noticed.

I ordered a pair of these this morning...... Gonna try 'em out here in the rural ranch country where I live. Maybe get some more additional peripherial lighting in addition to my PIT5374 headlight upgrade ......

And I also finally found the GM Part #23342527 on line at a GM dealer here in Texas and so, I ordered two more of the Vosla bulbs to have on hand for spares ....... I learned a long time ago out here in the "real" boonies, to have spare headlight bulbs on hand. I recently had two low beam bulbs go out on my 2005 GMC Sierra within 30 minutes of each other and I was 17 miles from the ranch. Made it home on the fogs and highbeams. Replace both bulbs next morning and immediately ordered new Silverstar Ultras for spares.....

I took my truck to dealer and got the BCM update and new bulbs. I tried it out last night in the country and will say it is a major improvement. Overall better brightness and peripheral vision greatly improved in low beam and high beam is major improvement. I still think the lights need to be aimed a tad higher as I still have the somewhat low sight line while in low beam.

I now have no complaints about this awesome truck.

BTW, my dealer said I was the third Sierra that he performed the update on.

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need.webcrimsNY

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
