Default Improve High Beam Alignment?

Owned 2002 & 2004 WRXs - now a 2005 Baja...replaced lo and hi & fog (Hella yellow bulbs) bulbs with “best” bulbs (Phillips?PIAAA?)...

Current high beams seem “crap” to me - sort of pointless actually...without ANY wiring mods/upgrades...can I adjust the high beam alignment to enhance low beam lighting?

That is, forget conventional high beam function (higher and further down road) in favor of more & better light on low beam projection - i.e. set up high beams so oncoming drivers not blinded - so be able to keep high beams on all the time?

Logic says just align high beams using low beam targets - so lower and further to right - taking into account hi beam projects a more diffuse beam (I believe) so perhaps even further to right than low beams?

I have minimal mech skills and no garage (gave up aligning after 3 attempts after bulb replacement🤪🤪&#129322 but can give it another go if it is possible.

Thanks

Low and high beams have a different beam pattern. So, aiming high beams so that its center "hotspot" lines up with low beam requirements won't produce the same effect.

But will enhance/brighten/widen without blinding oncoming drivers - correct?

I don't think so. The beam pattern, and I don't mean just how wide, but the intensity at different horizontal and vertical angles, of a high beam is such that if you aim even slightly lower than what it normally should be, the beam distribution would still produce glare, unless it is tilted so much that the usable hotspot will create very bright foreground that renders the augmentation pointless.

There's a reason why low and high beams have different patterns.

OP, what you are wanting to do will actually end up hurting your night vision by bouncing more light off the near-by road surface and into your eyes.

Satrya is right.

Besides the low and high beams are in the same housing and have to aimed together.

If you want more low beam light add some fog lights.

I asked my mech to check/align headlights w/o mentioning my “use high beams as low beams idea”...but lo and behold - that’s what I have now - essentially same “pattern”...so far have not been “flashed” by oncoming drivers (not a true test I know)...use low beam with fogs at dusk and in well lit cities...then switch to high beams elsewhere to light up ground 50-50 feet in front of me (so ok lowbeams)...don’t really have “high beams” now
