Headlight lightcone

So with it being summer and everything we have alot of sun out pretty much all the time here in Norway. It has to be late at night before it actually gets dark here.
So my experience with the Rebel in the dark has been.. well, none-exsistent.
Until now.
I am experiencing some frustration with the light on the bike.
The near light, normal driving light, is shining too close to the bike, at least thats what I feel when driving in the dark with it.
And yes, you can adjust the height, I know, and no, I havn't tried adjusting it just yet (mainly since I always forgets to bring the tool for it each time) But anyhow!
There is another problem here, and that is the far light, it bloody shines "straight up" into the night sky!
I'm seeing more of the road before me with the near lights, rather than the far lights.
And that gives me some concern, since the Rebel only has 1 bulb as it's light source for both the near and far light.
So by adjusting the near light upwards, then that would also adjust the far light even more upwards too.
And vice versa by wanting to adjust the far light down.

Has anyone else experienced simellar problem with the light on the Rebel?
I'm not quite sure how to go about this, it will be like choosing the lesser evil from two evils.

Nope, haven't had that issue... yours may be way out of alignment, causing the big difference between low and high beams. Also keep in mind headlight patterns have a fair amount of "bleed" beyond the beam, which allows for road signs to be illuminated.

It's important to know where the actual beams are set at, though.

Park on a flat surface about 30 feet or so from a wall. Stand the bike upright and measure from the center of the headlight down to the ground. Take note of this measurement and mark it on the wall in front of you. Make another mark 3 inches below that one.

Now get back on your bike, stand it upright, and shine your low beams at the wall. Adjust them until the top of the light beam is aligned with the bottom mark.

Now turn on your high beams... they should be fairly well centered on the top mark. If it's not, and is way off after having adjusted your low beam, I'd say somethin is wrong with your headlight reflector.

Yeah but that's the whole problem here, there is only 1 bulb in the housing, so when adjusting either one, you're adjusting the other one too.
But I'll be sure to get it checked out, sometime, when I finally manage to get going about dealing with it here...

Right, just get the low beam adjusted and see if the high beam ends up where it should be as well.

It may just be really far out of alignment. Think about shining a flashlight at a mirror... the steeper the angle, the steeper the reflection as well. This could cause the huge variance between the high/low beams. Fixing the angle may bring them closer together, as they should be.

So I finally got around to check out the light here.
And there is definitely something wrong with my high beam... Yey..
That one is waaay off into the sky!
But surprisingly the low beam was on point where it's supposed to be.
So I'm guessing there's gotta be a reflector out of possition.
Gonna take it back to the dealer when I'm back from vacation and let them deal with it.

To me it just looks like they're both a bit up...

Perhaps, might be..
My measurements might not be a 100% either thou.
I didn't want to adjust anything since the low beam was pretty much where it's supposed to be, and with the fact that I kinda want the low beam to light up a little bit more ahead of me. Even as they are now I feel like they are too close, so I really don't want them any closer
But, I might just have to give it a shot, just to see what happens.
Even thou, I'm sceptical, the reflector might add up for it, I dunno, but the high beam was way above where it should have been.
But, maybe 1 inch on the low beam will play out dramatically on the high beams position, who know's.

So I finally got around to try and adjust the height of the light.
And my god, what a pain that was...

The evening/night that I went to adjust it became a total mess.
I had set up everything, and looked in the handbook even, just in case you know.
I followed the book and started to adjust the screw. And I turned, and turned, and turned, and turned.... And the bloody light on the wall wouldn't change it's height. So I got frustrated and desided to take of the back of the housing, the black plastic, just to get a better look, maybe something is broken.
So I look around and I notise a secound adjuster screw on the other side, exactly the same as the one on the left side, as depictured in the book.
So okei, there is two of them, gotta be why I'm not able to make any change on the height then. So I start screwing on this adjuster bolt too. And I turned, and turned, and turned, you get where I'm going with this..
Slightly more frustrated now...
So I inspect the whole light assembly, to get a overview of how it's actually pieced together.
And I notise two screws, one on each side, that sits in the center of the housing, and those who holds the whole glass, bulb, etc, in place.
So okei, losen those two then, and then try again to adjust it's height.
And bloody freaking he*l you guys, one of those screws was placed there by satan himself...! Whatever I did, it would not nudge... I even broke my screwdriver.. The handle was just spinning...
So I had to get out the one under the seat of the Rebel.
And guess what..? The freaking tip of that screwdriver broke off!
So I gave up that night... I had had enough.
Tried again the next night, and brought with me every single screwdriver I could find in the house.
I won in the end! With the loss of some screwdrivers, but I won! Partially stripped the head on the screw too..
So when I finally managed to losen both of them, THEN I was able to adjust it's height without hassle!

And then I think back at the handbook again, with it's "how to do" manual.. WHAT A PIECE OF BULLSH*T BOOK!!
Why in the world would they not include PROPER guiding in it?! It is the bloody manual for crying out loud, it's supposed to contain the nesseseary information to do sertain things yourself!

Just to recap a little, for those who should be so unfortunate to have to deal with this themselves too;
1 - Remove the back cover on the headlight (2 bolts, one on each side "down bellow" on it, uses the same size allen key as the one that is on the bike, same one you remove the seat with)
2 - Loosen the two screws that sits on each side at the center of the housing (use a phillips screwdriver (never understood why you guy use such a name for it, sounds.. dumb. Here we just call them by what they can screw, so a flat head screwdriver, star head screwdriver, etc))
3 - Adjust the adjuster bolts to change the height of the light (Be aware here, since there is two of them. You don't want one of them to be adjusted more than the other. Safe option is to screw both all the way out (down) and then turn them both equally times in again until you're at the desired height of the light)
4- Back trace everything, remember to tighten firmly to avoid screws comming lose while driving.

I meant to get pictures taken of the prosess, but it was rather dark, so yeah..
But I could get some taken now, if someone want/need them.

Um, yeah, kinda forgot to actually mention here now, but adjusting the light down slightly helped in regards of the high beam!
Seriously feel like the low beam is waaaay too close to me while driving thou, but at least I'm not lighting up the tree tops anymore!
