The report identifies driver preferences for instrument cluster luminance/contrast levels. Thirty drivers (10 young Americans, 10 older Americans, and 10 Japanese) participated. Judgements (minimum, preferred, maximum, and dazzling) were obtained at nine sites along a 17-mile route in Ann Arbor, Michigan. Each driver provided judgements for 5 test conditions (daytime-elecronic cluster, with and without sunglasses; nighttime--electronic, green analog, and white analog clusters). Differences were found between young (64:1) and older (70:1) Americans, but not between American men and wommen or American and Japanese drivers. Prediction equations developed for contrast explain at least 84% of the variability for the preferred, maximum, and dazzling judgments.
