Is it acceptable to use old discontinued headlight aimers for inspection?

Using old discontinued headlight aimers for inspection is acceptable if they are in good working order. This means that as long as the equipment is functioning properly and can accurately measure the alignment of the headlights, it can still be utilized for the inspection process. The functionality and accuracy of the aimers are paramount, as the goal of the inspection is to ensure safety on the road by verifying that headlights are properly aimed.

It's important to note that while newer models may provide updates in technology or accuracy, the condition and operational capability of the older aimers take precedence in this scenario. Therefore, if they are maintained and used effectively, they can still serve their purpose satisfactorily.
