The height of the headlight doesn't matter. Headlights have a cutoff. Properly calibrated lights will have a maximum height of 2 inches below the center point of the enclosure at 25 ft. I had to do this recently for my WRX:

Most (all?) light bars are not SAE compliant and shouldn't be used on-road.

If you're getting blasted by a headlight, it's likely aftermarket and/or not installed correctly. This can happen with both car and truck headlights.
