What are the Critical Car Warning Lights

Among the things that we need to be cautious of would be the car’s dashboard lights. The warning light is the first indicator that something is not right. We’ve compiled the five most important warning lights that you need to watch out.


If you notice the oil pressure warning light is on, turn the car off and check the oil level of your vehicle. If you saw that the engine is making ticking, clattering or rapping noises, do not attempt to drive the car. Instead, bring the car for a repair. Usually, this warning light will mean that the oil level is low, but it can also say that there is a leak. Without enough engine oil, the pieces of your car will rub against each other and may cause permanent damage.


This light will show up if your car engine is overheating. The first thing to do is to pull over and turn the engine off. You need to open the hood and let the car cool down at least 30mins before attempting any check-ups. Usually, you need to make sure that you have enough coolant in the coolant reservoir and add mixture once you have confirmed that its running low. There can be other causes like a stuck thermostat, bad water pump, broken serpentine belt, defective radiator cooling fan, clogged or dirty radiator, exhaust restriction (plugged catalytic converter).


This warning light means that your alternator is not charging the battery. And you may only have 20-30mins left of driving before your battery runs out. Possible causes could be a bad alternator, a bad battery, a loose belt, a loose connection between the alternator and battery, or other electrical problems.


This warning light can mean that there is a problem with the brake’s hydraulic system. But if the light is intermittent, it means that the brake fluid level is getting low. Check the brake and release it. If the brake light comes on while you’re driving, it indicates that either the system is low on brake fluid, or there is a malfunction with your brakes.


This warning light means that you need to check the air pressure from each tire. Drive to the nearest gas station and inflate the car tires immediately. Do not disregard this light. A low tire can also cause uneven braking, uneven traction, irregular and rapid tire wear, increased rolling resistance and fuel consumption.
