Described are studies of the relationship between the level of foreground illumination provided by automotive headlamps and the driver's eye-fixation pattern and ability to identify objects ahead of the car. Analysis indicates that the driver's eye fixations tended to move further from the car at high levels of foreground illumination. There were no differences in distance of target identification as a function of level of foreground illumination.
