headlight aiming procedure
I replaced the headlights over this past weekend on my 1975 F250 Highboy and even though I did not touch the adjusters at all, the aim is way off and blinding oncoming drivers.
I whipped out my Ford shop manuals for the 75 trucks and the documented headlight aiming procedure is to use the "....Rotunda Headlight Aiming Kit Model TRE 540 with latest instructions dated June 1971..."
I recall back in the old days seeing a line scribed across the back of my local mechanics garage wall to do cars headlights.
Thinking this could work for a highboy if I knew what height and distance to set this line up on.
Anyone have a procedure for doing tis against the wall?
Thanks in advance

I use a set of Hoppy B4A headlight aimers on my old truck & cars. They are very easy to use & make a huge difference in headlight performance. I use them on my friends cars too when they stop by.
You can find them on ebay for not too much money if you do a little shopping.
I do have a set of really old Rotunda headlight aimers around here somewhere, but never used them.

thanks or the info; watched a you tube video on the Hoppy B4A , looks pretty easy to use and seems lots more accurate than aiming at a garage wall.
Found and bought the same Hoppy set off of Ebay for $25 plus 20 for shipping;
will post up my impression once I get it and try it.
Thanks,

Got the B4A kit finally and aligned my headlights.
The tool was a bit finicky to get set up initially and floor leveled, but once done it was very easy to use.
Headlight alignment was way off; it took all of about 5 minutes to dial them in.
Very pleased with lights now.
Thanks

Glad it worked well for you. It is amazing how much of a difference aiming with these tools makes.

I got my first set at a car parts swap. When I saw how well they worked, I started picking them up when I found them at the swaps & ebay-ing them.
When buying used, a few things to look for:
1) Each unit has three mirrors inside one end, make sure they are all there. Sometimes the mirrors are missing.
2) Make sure the suction cups are in good shape, not rotted or cracked.
3) Make sure you get the adapters you need for your headlights, & any headlights you expect to run across. Round & square take different adapters, as well as different ones for 2 & 4 light systems.
4) Carrying cases are almost always broken, if its the plastic case. Later sets came in a cardboard case. Not a big deal, just be prepared.
5) Some sets come with a cool light meter that tells you the strength of your bulbs output. I've gone thru 6 new identical Halogen bulbs & found about a 20% variation in strength. My truck got the strongest set.
6) Instructions for using them can be found online with a google search, if your set doesn't come with the instruction book.
Beartracks, I do have a nice set without a case for sale if you are interested. PM me.
