Dimension "H" is a measurement you physically have to measure. It assures your truck is level when adjusting the lamps. If you measure (just an example) 3'-0" from the ground to the actual haedlight center, then 25' away on the screen, the beam should be at 3'-0"...then your truck is level. Then the "Allowable vertical Aiming Area" should be between 2.094" below the measured "H" and .5" above "H". That is the way I see it from an engineers point of view.
