Abstract

A traffic light alert system of a vehicle includes a display operable to display an iconistic traffic light representation with a background surrounding the displayed iconistic traffic light representation. A control is operable to adjust the display responsive to a determination of a status of a traffic light ahead of the vehicle and being approached by the vehicle. Responsive to determination of the traffic light ahead of the vehicle and determination that the traffic light has a particular signal status, the control controls the display so that the iconistic traffic light representation indicates the determined particular signal status and the surrounding background is displayed in a particular color associated with the determined particular signal status.
