As for the owner's manual, it appears that it only mentions the LED adjustment, likely because it doesn't use the same method as our halogen models.
The manuals don't change model to model, just all encompassing and for specific options or trims have them shown as (if applicable)

For example, the many different gauge clusters are shown

I am curious though, does everyone's owners manual match the trim of their car as the cover? My 2022 has a Sport Lithium Red Hatch on the cover, matching my car...

 

Same as my manual. Am I reading the heading wrong because my interpretation is everything written afterwards pertains to the LED lights

 

So I took a look at the manual, because surely the LED (Auto levelling) headlights aren't the only headlights that can manually be adjusted.
Manual does in fact say only specific models have the ability to adjust headlamps.

However I took a look at my halogen headlamps, and am wondering if there is a method to adjust them, ideally without taking the vehicle to a dealer. Especially since headlights do need to be adjusted regardless of type. The piece I found in my car has a green 'plastic screw' with no wires coming off it, and situated between the low/high beam. Exists on both sides, but easier to view driver side. It also appears to be in the same position as the LED headlight adjustment mechanism... though that is if I'm reading the manual correctly.

Anyone with the LED projectors able to confirm?

 

I have the exact same adjustment thingy as you do. Problem is that I can't find anything about it

 

Just installed Beamtech LED headlights

Just finished installing and adjusting Beamtech LED low beam headlights which I purchased on eBay. Stock low beams Left Beamtech low beam (H-11) installed pointing a bit high. Turned blue adjuster counter-clockwise with a 6mm allen key which lowered beam to match right side. Installed...

Adjusting Headlights.

My 18 Impreza rarely carries any passengers or weight so the headlights are a little lower than I would like. A little higher would not only make my lights more effective it would help me be seen in the Sea of SUVs and trucks. I'm not talking a lot, just a few degrees of upward tilt. Anyone...

Did a search to see if anyone else mentioned this, it appears that this is in fact the adjustment mechanism. Uses a 6 or 8mm allen (hex) key.

 

Ahh ok makes sense now.

 

When the weather improves, I'll have a look, so see if the adjustments are there.

It could be the manual says to have the dealer do it because there is some special equipment that is supposed to be used to ensure aiming. Don't know why they don't say the same for the LED bulbs.

 

Shouldn't be special equipment, seems that it's a 6-8mm hex... May be a way to draw you in to the dealer for service, but idk, headlight adjustment is easy to do, (and easy to mess up) if you're not sure how to do it.

 

Found it. Here is a shot of the driver side, looks like a #2 phillips screwdriver will do the trick. Only thing is, which way would raise the headlights aim?

 

Special equipment, as in, aiming tools; things that make it simple enough, one only needs a grasp of with they're doing. But, yeah, if you understand the process, aiming is not hard.

 

This thread is not new, but I did find an adjustment for the halogen headlamps in the service manual, height only; (b) is the light source center, (d) is the height of the source center, and (c) is 10 meters.

 

does it say which way to turn to raise the headlight? Also where did you find a Subaru service manual?

 

No, but it should be obvious when you turn it the wrong way. To make it easier, I block the other light so that only the one being adjusted shines on the wall.
