Headlight Aiming

[Kevin Sheehan]

When I leveled the front end of my 2500, before I did any work I drove into my garage, turned my lights on and using electrical tape marked the floor where my front tires were, then the wall above and below the brightest portion of all the lights including the fog lights. Made the change to my keys and shocks. Leveled the truck, then turned my lights back on that are now higher on the wall, adjusted them down using the screw mentioned behind the light fixture until the beams are exactly where they were stock.

Pictures as mentioned above. The Allen wrench is a 6 mm, roughly 6 inches long. 

Do you happen to recall which direction screw turn was up vs down?

This procedure likely has your headlights pointing down a bit more than they should, unless your garage has a LOT of space between the headlights and the wall you put the tape on.

I don’t, but as soon as you start turning the adjustment it should be obvious which way it’s moving. 
 

Whenever I do an adjustment like this I count turns so I can put it back where it was if I decide I screwed something up.

Is there any provision for adjustment from side to side like typical headlights in the past were designed like or is there only a vertical adjustment. I haven't had reason yet to adjust my lights but I also haven't used it much at all in the dark either, however I did have someone flash me right after I bought the truck and found that odd as its not like I had any weight of consequence in the truck or had modified anything which I did slightly after as per doing a slight adjustment on the front torsion bars which did raise the front end slightly. The adjusters I do see which would be for up/down are quite easy to access, be it a 6 mil bit on a 3/8 extension or a typical 6 mm allen wrench, yes it has the Philips drive but it is plastic after all and pretty dinky looking.
