Abstract
A sensor is configured to monitor an intensity output of a light source of the head-up display and provide a measured actual light intensity value to a controller. The controller is configured to store a target light source intensity value in a computer-readable memory. The controller is configured to compare the measured actual light intensity value to the target light intensity value. The controller is configured to reduce the light intensity output provided at a vehicle operator viewable display surface in a situation where the measured actual light intensity value exceeds the target light intensity value.
