A headlamp aimer box includes a housing defining an opening and a tunnel, a window disposed within the opening, and a whiteboard disposed at one end of the tunnel. The box further includes a mirror disposed within the tunnel. The mirror redirects a beam passing through the window from a headlamp toward the whiteboard. A length of the tunnel is such that light patterns directed by facets of the headlamp sufficiently cross a median line associated with the headlamp to form a developed beam on the whiteboard.

A method of aiming a light source includes using an image-capturing device to capture a light beam pattern from the light source. Here, the light beam pattern is configured to include a plurality of contrast ratios transitioning from a first intensity region to a second intensity region. The method includes processing the contrast ratios of the light beam pattern to obtain corresponding values of the contrast ratios, transitioning from the first intensity region to the second intensity region, where the corresponding values are logarithmic values, which in turn generate a related response curve. Finally, the method provides for using the logarithmic values and the response curve to aim the light source.
