Is there a way to aim the headlights on the 2020+ Sierra HD’s?

I get flashed occasionally with an empty box  and all the time as soon as I get a few hundred pounds in it. It’s currently stock suspension and height so I can’t imagine what’s going to happen if I level it.

I've not had that happen to me since I got my Sierra, but I did get it a few times with the Silverado. I think these lights are so sharp and bright, many motorists think they are on high. Most times, it was when pulling my fifth wheel, but once I put the Timbrens on, everything went back to normal. Hope this can be of some assistance to your question.

Not really lol. I can see it in the tree line and on the highway that when the truck gets loaded the lights come up. So they have to be getting brighter in peoples eyes.

Not sure if the Sierra is the same as Silverado, but on mine if you look straight down behind the headlights inside the hood the is a white nylon cone about 1-1/2” in diameter. At the bottom of the cone is a small slot for a bit (I can’t remember if it is a torx or Allen type). Turning the cone raises or lowers your headlights, mine was really easy to do

I didn’t see anything but I’ll take a more thorough look. My gm tech buddy says he hasn’t had any complaints so hasn’t had to look into adjusting one but seemed to believe the gmc didn’t have any adjustment capabilities.
 

i don’t understand why with all the technology they throw at these trucks like knobs for dummies who can’t back up a trailer and such that they don’t have auto adjusting headlights. Or at least a switch to do it from the cab.

You were right. Last time I ever take a gm techs word. 
Its not white but there definetly is a spot to adjust it. When it gets dark and I figure out which way to turn it for up down I’ll report back.

until I figure out how to add a picture to my post, here’s a link to the image I took this morning. I looked a little closer and it’s a Phillips down in the bottom of the cone. Good luck all

Looks like a little different setup for the Sierra but I’m glad you found it

So you can just turn the cone?.....which way for down if you find out would be helpful

 

 

GMC adjustments are higher up  and use phillips.....there is vid showing GMC

Yes just turn the cone with a philipps. I don’t remember which direction was up or down, I just aimed them at my garage door at night to figure it out

The screw turns in the direction you need the light to go. Clockwise will turn the bulbs down, counter clockwise raises them up. If your getting flashed with brights, adjust the higher one down to equal with the lower of the two.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      By dna9656 · Posted

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

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

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      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.
