An instrument cluster is a collection of gauges and displays located on the dashboard of a vehicle. It provides essential information to the driver, such as speed, fuel level, engine temperature, and warning lights. This helps the driver monitor the vehicle's performance and make informed decisions while driving. Modern instrument clusters can also include digital displays that show additional data, like navigation directions and trip information. Some advanced clusters are customizable, allowing drivers to choose what information is most important to them. Overall, the instrument cluster plays a crucial role in vehicle safety and efficiency.
