The engine is the most essential part of a car, and seeing the engine light on is most drivers' worst nightmare. The warning comes on in the shape of a silhouetted engine. However, sometimes, it illuminates with the all-caps message "CHECK ENGINE."

The warning could be related to the car's emissions and motor system, a loose wire, a worn solenoid, or a severe engine problem. If the check engine light pops up while driving, proceed to the mechanic for a proper diagnosis.

2. Battery

The symbol is also known as the transmission temperature warning light. This yellow light on the dashboard appears like a thermometer taking a dip in the ocean.

The warning indicates an overheated car. The reason for this could be a broken water pump or coolant levels going down in the radiator. It could also mean a leaking or burst coolant hose or a damaged radiator.

4. Traction and stability control

The warning light often appears as a front view of a car, with two squiggly lines underneath. This illustrates that your car is sliding on the road. The traction and stability control light only turns on when the system is active.

The cause could be excess water due to rain or snow. If they turn on when your car is not speeding and the road is dry, there could be an issue with the system, and you should have it checked.

This is the most visible warning light on the dashboard. When the oil pressure light illuminates, it indicates that your car needs oil to be topped off, that the oil pump is broken, or that there is a leak of oil in the engine.

When this happens, check the oil levels using the engine's dipstick. If it shows oil levels are low, add oil, and hopefully, the light will go off. If that doesn't happen, get to a mechanic for a proper diagnosis.

7. Tire pressure monitoring system

The light appears as a two-thirds of a circle with an exclamation point at the centre. The lines at the bottom symbolize the tread of a car tyre. It could mean that you have a flat or overinflated tyre, and it is hazardous to drive with tyre issues.

Stop and refill the tyre to the ideal pressure rating if you see this sign. Reignite the car to see if the light goes off. If not, the tyres may be damaged, and you must replace them.

This is also among the most dangerous lights for many drivers. Brakes are critical in a car, as they help slow down a vehicle on the road and when changing gear. The light is a form of communication that indicates your brakes have an issue.

Stop and check to see if your parking brake is engaged. Then, try releasing the brake while in the park. If the light doesn't go off, take your car to the mechanic.

It could be that the driver pulled away when the parking brake engaged, worn-out brake pads, low fluid, or a faulty Anti-lock Braking System (ABS). If the ABS light is illuminated, your car has a problem with the ABS.

The light automatically turns on when the car is started. However, if it stays on while driving, your airbags have a problem. Although this will not stop your vehicle from moving, it could pose a danger in case of an accident. You should, therefore, have your car checked to ensure your safety in case of an accident.
