<VV> Headlight aim correcton

[JVHRoberts at aol.com]

Well, those sealed beams aren't exactly the vanguard in optical technology.

With those fuzzy beam patterns, don't expect much. 
 
But you DO, in fact, align the outer headlights for best low beam aiming,  
and the inner headlights for best high beam aiming. 
And the high beams in the outer headlights are nowhere near as good as the  
inner headlights. I think it would have been better if they were designed  
optimally as low beams ONLY, and high beams ONLY. Like a lot of today's cars,  and 
Euro cars of the era.

Well,  well, well,

I was just going to modify my original statement ("So, the  adjustment is 
done with the high beams on and the low beams  are

automatically focused correctly.")with adding "or vice versa" to  the end. 
This would make it correct.

But, you two seem to think that  there is something in the manufacturing 
process that makes the high beam focus  a wild card, not to be trusted. Well if 
that was the case, then somebody  better go back and check that filament 
alignment jig, as both filaments are  supposed to be focused as built. (Remember 
Pre-Focused lamps before sealed  beams?)

As proof, I offer up the 65 shop manual page 12-2. Here it  describes 
aligning the lamps using the tool Harry has for sale. Both No. 1 and  No. 2 sets of 
lamps (inboard and outboard..hey now he's talking boating...)  are aimed to 
give a 2" drop of the headlamp high beam spot centerline on a  screen placed 25 
feet away. Hence this shop manual is saying the high beams  are adjusted and 
the low beam is automatically adjusted at the same time.  

Of course now I need to correct my first post, as there I said to make  the 
high beams hot spots level at 25 feet.... make that hot spot should be 2"  
lower than center of headlamp. Of course you are warned to check your state  law!
