Adjusting 2014 Sierra headlights left and right

[SierraRover]

Lots of discussions on the web about raising and lowering the aim on the 2014 Sierra projector-type headlights. I found the two adjusters for height... but I cannot find any way to adjust the left/right aim.

 

My left (driver's side) headlight is off into the oncoming lane. Pretty comical, really. There is a dark gap between it and my right (passenger's side) headlight, which seems about right. I want to bring the left side in a few degrees so it lights up the centerline of the road -- but I cannot find an adjustment point.

 

Any ideas?

 

Thanks!

Yeah I'm in for this as well. Any guide or advice or how to aim them?

I'm having the same issue on my 2014 Sierra All Terrain. The driver side points off into the woods (I have rotated the bulb several times to fix). I installed a Morimoto HID Kit and I think I am going to rummage around in there to see if I can locate a horizontal adjustment. If I find anything, I'll update this thread. Have ya'll found anything yet?

There is only adjustment up and down. Not left to right.

 

If your beam patterns are wonky, it could be from the bulbs not being seated correctly in the housing. Get in there and make sure they are seated 100% correct. I had an issue one time (self induced) where I took out a bulb to inspect the housing. I put it back in and I thought it was right, but I had actually got one fin of the bulb missing the correct seat and it was making the beam shine way off to the side. After I reseated it the beam was straight forward.

 

FYI, how to adjust up and down correctly.

Question and sorry to hijack BUT are the high beams supposed to cross one another?? Mine now point in the tree tops after level and it is very noticeable how they cross....just wondering??

So, Fondupot is correct. Sorry it took so long for me to reply. If your lights are pointing the wrong direction (left or right) you need to really look into the housing and see the tabs he is talking about. Once I climbed into the engine compartment to get a good look, I saw my problem. You will have to work with it a little to get it set just right, but once you do, they are aimed in the right spot. Highbeams should not cross and if you adjust the up and down, the highbeams will shine dead ahead and not up into the tree tops. I highly recommend an HID kit upgrade or an LED upgrade. I went with Morimoto from www.theretrofitsource.com, but I wish I had gone with the LED upgrade from the same location. VLEDS has matching fog lamp LEDS at a reasonable price, but you may have to switch your factory o-rings out to make them fit. Hope this helps!

 

As an FYI: I have the Rough Country 2" leveling kit, so I did have to adjust my headlamps. It took awhile and many oncoming highbeam flashes, but I have it now. It was literally trial and error with me.

My high beams continue to be up in the trees, but my low beams are doing a better job since I got the TSB done. Bottom line, these are not stellar headlights. They can be made to work reasonably well with the TSB (see http://www.gm-trucks.com/forums/topic/165447-headlight-illumination-issues/page-96 for details) and some careful efforts to raise/lower their aim as necessary. The pencil tick marks on my garage door attest to my efforts to get the low beams in the right location over several adjustments.
