Do you guys get flashed a lot?

(no not that) :lol:

 

I've had a few people in the last month flash their high beams at me and I'm wondering if the low beams being "stacked" above the high beams on our trucks may be causing people to think the high beams are on just because they are the higher lights?

 

Now... I did re-aim them right after buying my truck last spring (becuase the lights suck compared to the projection lights I had on my last car) and then I did lower the rear suspension... so I'm sure I deserved the few two times it happened. But I have since aimed them noticably lower and I still had someone flash me.

 

Have you guys had any issues? and how do you like to aim your lights?

Nope. Lights are way too dim on low to ever have anyone flash me. No confusing high and low beams on these lol. The Gmc's are so pathetic that a lot of guys just leave their highs on... and still don't get flashed. At least the Chev like mine has the second bulb.

I notice with my vehicles since 2011 that if you are going up a slight incline the people coming at you think you have you highs on. I notice the same when they are coming at me on secondary roads. When I ask the dealer they say lights are normal I just lower them a little.

I have a Sierra and after the ECU update and Volsla bulbs I get flashed every night. I adjusted them up a little (not even half rotation) because they were so poor before the update so I need to adjust them down again. I'm still not that impressed with the light output...

a truck being good will get the flashes.

 

I have a 96 that lights up 2 miles ahead (I am not kidding)

 

those tiny lights known for being dim..

 

 

its not up or down as much as peripheral. Aim the driver side against towards the middle after getting them right.

Every d*mn night. It's getting really annoying. I have a 7" lift though, so I guess it comes with the territory. I did adjust them down but still get flashed constantly.....at which time I give them a dose of the actual brights hahah.

Don't they have headlight height laws where you are? I think they add hidden headlights under the bumper on those really tall trucks.

 

 

I bought a set of aftermarket fog lights to help illuminate things. There's not much to bolt to though so I'll have to build some brackets to locate them in the factory spots.

Twice now within a week of ownership. I wonder what they'll do when I switch out to some legit bulbs.

Your 2012 has decent reflector lights. Yeah they're not projectors. But at least they're not weak halogen projectors like the 14-15 Sierra. You can do a bulb upgrade (still halogen) from the stock one and increase the light significantly with good beam control (unlike a HID in a reflector).

 

To aim them, find a level and very smooth parking lot or road. Measure to the center of the headlight from the ground on both sides. Go out in front about a length of the truck, use something like a large sheet of cardboard for the beam to project onto, Place the sheet of cardboard on the ground and measure up to the cutoff. It should be noticeably lower than the center of the headlight. About 4" lower should be around the right amount. Due to irregularities of the surface of the pavement, you can get variability in the measurements. You should check it in several locations (various surfaces).

You also have to adjust the sideways aim of the headlight.

Low beams should be aimed slightly to the right.

 

If you are aiming your headlights as spurshot has suggested above you also need to adjust the light slightly to the right about 2-4 inches. this will require you to make sure that the vehicle is perpendicular to the surface you are aiming at. Mark the aiming surface where the center or the sides of your vehicle would be located for a measuring reference.

      OCI, not when but why?

      By Grumpy Bear · Posted

      I understand. It is disturbing to think a manufacture asks so much and gives so little in engineering support. This is not a GM issues, this is a greed issue and one the ALL practice.    My intent was not to remove the wind from anyone's sail but rather to point out the areas deficient so that they can be discussed with improvements the goal. But to do that you have to know the truth and what that truth is.    The commercial interest are honed in on a few select issues in which they control all the variables and are not forthcoming in the least with their customers about the details. Failure is the only thing that drives these people to improvement. One way not to fail it to manage public "expectations". The set a bar they can clear and put their thumbs under the suspenders with chest puffed.... Only the internal data tells the story fully. As we don't have access to that for decades then we have to generate it ourselves. UOA's with data that matters.

      OCI, not when but why?

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...
