This SAE Recommended Practice provides laboratory test procedures for testing headlamp aim test machines to verify their ability to aim or to inspect the aim of headlamps, fog lamps, and auxiliary high beam lamps. This specification does not apply to aiming devices of the kind covered by SAE J602. This specification does not apply to motorcycle headlamps.
Added “This specification does not apply to motorcycle headlamps.” to the Scope
Removed “bonded” from RBHL definition of Section 3.3
Added reference to SAE J1383 regarding Group I and Group II aim pads of Section 3.4
Modified 5.1.1 changing “specified” to “the following”
Expanded to the use of photometry test results as a method for determining equipment compliance in Section 5.1.3.
Added relevant definitions and updated terminology from SAE J387 and SAE J1383
Included a broader range of test lamps to include recently developed types of headlamps
Included SAE J599 aim method since the headlamp aimer often is a screen replacement
Permit compliance of aim accuracy if the headlamp aim machine positions the test lamp such that it complies with the relevant photometric requirements
Decreased the accuracy required for alignment
Increased the lower limit of aim machine vertical height range
Removed references to SAE J582 “Auxiliary Low Beam Lamps” which was cancelled July 2005
