Not all car warning lights that come on mean that your vehicle is broken. Also, being mindful of them daily can help prevent accidents. Be sure to learn about warning lights so you can deal with them calmly even if they come on while driving.
What are these Warning Lights for?
A car’s warning lights, pop up or flash to alert the driver when there is a malfunction or other problem with the vehicle, or when the driver makes an incorrect operation. There are global standards, and although there may be slight differences depending on the manufacturer, the design of car warning lights is almost the same for both domestic and imported cars.
The Urgency of a Warning Light Varies Depending on its Color.
The colors of warning lights and indicator lights are defined by international standards (ISO) as three types: red, yellow (orange), and green, and the level of urgency varies depending on the color, as shown below.
- Red: High-urgency trouble. You must immediately stop the car in a safe place and contact a dealer or repair shop.
- Yellow (orange): A problem that does not require you to stop driving immediately, but does require immediate inspection.
- Green: Safe condition for driving without any hindrances.
Even if you don’t understand what the warning light means, if it is red it indicates an emergency, so be careful not to overlook it.
Warning Lights to Look After On Daily Basis
Now let us show you the list of car warning lights that you should remember, these are sorted by their emergency level. These warning lights often come in front of us in our daily life and these are a little risky if compromised.
Seat Belt Unfastened Warning Light

This light comes on if the driver or front passenger is not wearing their seat belt. Make sure to fasten your seat belt securely until you hear the metal part click into place.
Recently, weight sensors installed in the seats have been used to check whether there is an occupant or not. Therefore, even if there is no one in the car, the warning light will come on if there is heavy luggage or the like.
Door Ajar Warning Light

Door warning light comes on when the engine is on and the driver’s seat, passenger seat, rear seat door, back door, etc. are not completely closed. If the light comes on even though you think you have closed them properly, check to see if there is anything caught in the seat belt or clothing.
Fuel Level Warning Light

Fuel level warning light comes on when there is little fuel left. The amount of fuel remaining when the light comes on varies depending on the vehicle model, so please check the instruction manual. If the vehicle stops due to running out of fuel, it can cause an accident, so do not think that you can continue driving for a while even if the light comes on, but fill up the tank immediately.
If the light comes on after refueling and you have not driven for long, gasoline may be leaking. Turn off the engine in a safe place away from fire and check around the fuel tank.

Tire Pressure Warning Light
