A dashboard warning light is a visual indicator on a vehicle's dashboard that alerts the driver to potential issues. These lights can signal various problems, such as low oil pressure, engine overheating, or issues with the brake system. Each light typically has a specific symbol or color, making it easier for drivers to identify the nature of the problem. When a dashboard warning light illuminates, it is important to address the issue promptly. Ignoring these warnings can lead to more severe damage or safety hazards. Drivers should consult the vehicle's owner's manual to understand the meaning of each light and take appropriate action, such as seeking professional assistance or performing basic maintenance.
