Leveling - headlight aiming

[1940ModelB]

In all the excitement of installing my new shocks, I forgot to measure my headlights prior to leveling my truck and now have no clue where to aim as a starting point.

 

Does anyone have measurement I can use to re-align these things? 

 

For reference, the truck is a 2018 Silverado 1500 LT Z71

Pull the truck on a flat surface facing a wall approximately 25' away.  Measure the distance from the ground to the middle of your headlight.  Go to the wall and measure the same distance from the ground and put a piece of tape on the wall.  Adjust the headlights until the top of the beam on the wall is just slightly below your mark.

Yup, this above methid is universal for all vehicles and best way to align them. From there you can fine tune by adjusting up tiny bit at a time to get little more light down the road but pull back when you start getting flashed.

So is the process the same for a truck that has been lifted? I just put a leveling kit on my truck and I know the headlights are too high now. So I still measure to the middle of the headlight for the height to aim for on the wall at 25ft or is that only for factory ride height? In other words let's say someone lifted a truck 6". That would put the center of the headlight at least that much higher than it was before. So if this methed is used wouldn't the cutoff at 25ft be way to high in relation to passenger vehicles? Or am I overthinking this?

I have always used the same method regardless of the height of the vehicle I am doing it on.

OK so do you use that little indentation on the face of the housing as the height marker?

I don't use any marker.  This isn't a precise thing.  Just measure to approx the center of the light.
