This category encompasses instrumentation for monitoring vehicle performance and timekeeping. Gauges utilize sensors to display critical parameters like engine temperature, oil pressure, and voltage, typically integrated into the instrument panel. Clocks provide time indication, often digitally displayed and synchronized with vehicle systems. Knobs control various functions—lighting, climate, audio—and feature tactile interfaces coupled with electromechanical or electronic switching. Modern iterations increasingly incorporate backlit illumination, digital displays, and CAN bus communication for data integration and control. Durability standards require resistance to vibration, temperature extremes, and UV exposure.
