auto.headlight-aim Calculator
Calculates the correct cutoff height on a wall at a given distance to aim headlights so the beam illuminates the road without blinding oncoming drivers. Most MOT failures from poorly aimed headlights can be avoided with this check.
Inputs
Distance Ft
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Headlight Height In
Vertical measurement. For health calculators, typically standing height without shoes.
Aim Drop In Per Ft
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Results
cutoff height at wall (in)
The computed height.
downward aim angle (deg)
The computed angle in degrees or radians.
wall distance
The computed distance or separation.
headlight height
The computed height.
NHTSA standard
Sample size or count used in the calculation.
check
A pass/fail verification against the applicable code, standard, or threshold.
