Modern cars are equipped with dashboards that provide vital visual alerts to drivers about the health of various vehicle systems. Warning lights on the dashboard can range from less urgent indicators to critical alerts signaling severe malfunctions requiring immediate attention. This article discusses the most crucial dashboard warning lights that demand you stop your car immediately and take action, helping you avoid costly damage or serious accidents.
How Dashboard Warning Lights Work
The dashboard contains warning lights linked to sensors that monitor components like the engine, brakes, oil pressure, steering, and electrical systems.
Color codes matter:
Red lights: Demand immediate stop and service.
Yellow/Orange lights: Signify a problem that needs inspection soon but may not be an emergency.
Green/Blue lights: Indicate normal functioning systems.
If a warning light stays on continuously while driving, this is a red flag to get the car checked promptly.
