Abstract
The present study was designed to investigate the customer preferences related to headlights, as measured by J.D. Power and Associates 1998 Initial Quality Study (IQS) - (“Headlights not aimed properly” question). We investigated beam patterns that ranged from high to low customer preference. As a result of our investigation, we have developed guidelines for desirable beam patterns for the U.S. market in terms of the sharpness of the cutoff, the foreground brightness, and the total flux value.
