Abstract
A method for aiming headlamps on a vehicle achieves a reduced variation in beam heights without making any changes to existing test equipment. A cutoff height of a first headlamp is measured. The first headlamp is adjusted until a first measured cutoff height is within a predetermined range centered on a predetermined fixed height. A cutoff height of a second headlamp is measured. The second headlamp is adjusted until a second measured cutoff height is within the predetermined range centered on the first measured cutoff height.
