Abstract: A vehicle instrument panel assembly that includes a display, a pointer, and a light detector. The display is configured to define indicia on a surface of the display. The indicia are configured to emit light. The pointer is configured to rotate a shaft of the pointer about an axis to align a tip of the pointer with the indicia. The pointer is also configured to conduct light emitted by the indicia from the tip into the shaft when the tip is substantially aligned with the indicia. The light detector is configured to detect light in the shaft of the pointer to determine the position of the pointer.
