Instrument Cluster:
An instrument cluster, also known as a dashboard, is a panel located behind the steering wheel of a vehicle that displays important information to the driver. It typically includes various gauges, indicators, and warning lights that provide real-time data about the vehicle's performance and condition. The instrument cluster is essential for monitoring speed, fuel levels, engine temperature, and other crucial aspects of the vehicle while driving.
The instrument cluster usually consists of a speedometer, tachometer, fuel gauge, temperature gauge, odometer, and various warning lights such as the check engine light, oil pressure light, and battery light. Modern vehicles may also have digital displays that show additional information like navigation directions, entertainment settings, and vehicle diagnostics.
