Warning Light for Oil Pressure
Never neglect this light because it is the most critical warning light of all. And yes, you guessed it right; it comes in red! It looks like a lamp with a drop of oil dropping from the nozzle.

Oil pressure is created because of the oil pump and the amount of oil in our engine. The oil pump is essential because it keeps the engine oil in motion. Hence, any leakage, too little or too much oil, or even a faulty pump triggers this signal.

If you’re concerned about the costs of repairing your car, consider looking into diagnosing and repairing it yourself by watching various DIY mechanic YouTube channels or a trusted website such as YouCanic. These experts can empower you with detailed instructions for all kinds of simple car repairs. Then you can become your own car mechanic at least for minor problems and overall maintenance. Of course, you will need a laptop and some tools.

Warning Light for the Brake System
This warning sign is typically red, but this time it includes an explanation (!). If it appears after you start the engine, do not proceed. If it appears while you’re driving, quickly pull over to the side of the road. The vehicle must be towed to a mechanic immediately.

Certain vehicles may also display the (P) symbol instead of the exclamation point (!). Therefore, what does the (P) symbol indicates? This indicates that you have not deactivated the parking brake. If you have, though, and the signal continues to display, pull over. Then, visit a local auto repair to resolve the problem.

Warning Light for Battery Charge
This warning light is also red and looks like an outlined battery with one positive sign and one negative sign (+-). This signal indicates issues with the car’s charging system and the battery. So yes, it is exactly what the sign shows.

However, apart from a faulty battery, the issue can also arise due to faulty wiring. And, if things are more serious, there could be an issue with the drive belt or alternator.

It could also reciprocate in the weak engine that is unwilling to ignite every time. In this scenario, it is essential to pay a visit to your garage with your car.

This problem could also easily be seen at night when you notice that your vehicle has dimmer than usual or even dying headlights. If it is just one headlight with an issue, it could simply mean that your bulb needs replacement. Learn more about which headlight is best for your car.

The car won’t stop beeping until you or your passenger have fastened the seat belt. So yes, even though it is annoying, the constant beeping is needed to encourage everyone to buckle up.

Warning Lights for Door, Trunk, or Engine Lid
