TL;DR - 42" at 75' and don't aim them up.

2. Location of headlights.  On a motor vehicle, a headlight must be located at a height, measured from the center of the headlight, of not more than 54 inches nor less than 22 inches above the level surface on which the vehicle stands. Headlights on snow plows may be at a height greater than 54 inches.

5. Requirements.  The following requirements apply to a headlight.
A. If the vehicle is mechanically constructed so that it is limited to less than 15 miles per hour, it must have headlights capable of furnishing sufficient candlepower to render any substantial object clearly discernible on a level way at least 50 feet directly ahead and at the same time at least 7 feet to the right of the axis of the vehicle for a distance of at least 25 feet. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
B. If the vehicle is mechanically constructed so that it can exceed 15 miles per hour, it must have headlights capable of furnishing sufficient candlepower to render any substantial object clearly discernible on a level way at least 200 feet directly ahead and at the same time at least 7 feet to the right of the axis of the vehicle for a distance of at least 100 feet. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
C. A headlight capable of furnishing more than 4 candlepower, if equipped with a reflector, may not be used unless the headlight is designed, equipped or mounted so that no portion of the beam of light, when projected 75 feet or more ahead, rises above a plane of 42 inches higher than and parallel with the level surface on which the vehicle stands. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
D. The top of a main beam of light may not be higher than the headlight center. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
E. An electric bulb or other lighting device of a greater capacity than 32 candlepower may not be used, except for the standard equipment sealed beam unit. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
F. A headlight may not project the top of a main beam, at a distance of 25 feet ahead of the vehicle, on an approximately level stretch of highway, onto the body of a person or an object, at a height greater than that of the center of the front light from the highway. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
[ 1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF) .]

The inspection manual lists out the requirements for aim.  I'll look for it in a minute.  That being said any inspection station is supposed to have a aiming machine or chart.

The best way is to use headlight aimers. I always adjust mine down slightly from "correct" but due to the height of the Jeep you will always have drivers in cars getting blinded
Jeepin ain't easy

I was talking to another member about getting flashed by oncoming traffic due to low beam height.  Can one of you inspection mechanics tell us the way to adjust properly please and thanks
