The meaning of the car witnesses

Fans of the famous series The Big Bang Theory they will surely remember the scene in which Sheldon, one of the protagonists, travels with Penny, another of the most famous characters in the series, in her old car. Sheldon realizes that his engine light is on and alerts Penny, who ignores his warnings until the vehicle eventually breaks down.

Without a doubt, it is one of the most famous scenes of the entire series and, despite the humor with which it raises the problem, the car drivers they can indicate real problems to watch out for. However, not all drivers know the meaning of all the symbols that can be illuminated on the instrument panel.

This is the meaning of the lights that can be turned on in a car.


The motor pilot is perhaps the most recognizable of all. Their amber light appears in the situations in which they are logged abnormal engine related parameters. For example, this light indicates faults in the exhaust gases, the ignition or even the injection system. If it does not disappear after stopping for a while, the best option is to take the car to the workshop.


This warning light warns that the engine must be preheated. If it lights up, you have to wait for it to turn off to start the engine. In the event that it lights up or starts to flash, it could warn of engine faults, so the car would have to be stopped and taken to the workshop.


This warning light warns with a red light that the Oil pressure is lower than necessary for proper engine lubrication. In some cars it turns on while the car is started and then turns off, so there is no need to worry. When its light persists, it indicates that there is practically no oil in the crankcase and can cause significant problems.


Another of the most recognizable. Also red in color, this indicator lights up when the alternator has a problem and it cannot recharge the battery or provide enough power for the car systems. If this is ignored, the driver will probably run out of battery in a short time or the car may even stall while running.


This witness has no mystery, it will always be on when the parking brake is on. Depending on the manufacturer, the symbol may change and replace the exclamation point with a ‘P’. When it comes on, and the parking brake is released, it may be because the brake fluid is low. An amber-colored, no-exclamation-like light can illuminate when the brake pads are worn.


This warning light alerts, with a red light, that the coolant it’s hotter than it should, in case the liquid level is low or not present. If it is for the first case, the best option for the driver is to interrupt the march, stop the engine and let it return to a suitable temperature.


As its name suggests, it will only light on cars with diesel engines. Its ignition will indicate problems with the particulate filter.


This amber light does not come on to indicate a fault or problem, but simply alerts driver that fog lights are on, which should be turned off when low visibility conditions do not occur.


It lights up red, like the faults, but it is not a fault. This witness warns that some of the passengers are not wearing a seat belt and that it should not be started to prevent fines and serious injuries in accidents. Normally, in the passenger seat, it is accompanied by an acoustic signal when starting.


This indicator lights red when an airbag is not working properly. In cases where the passenger airbag should be deactivated, such as when there is a child restraint system, the light will stay on all the time.


He is a more or less new driver that cars have been incorporating for a few years. With its light it indicates that the vehicle tire pressure is incorrect. To solve the problem, just check which one is affected and inflate it. Its light is useful for detecting punctures.


Similar to the handbrake but with the letters ‘ABS’ inside. This pilot indicates that the antilock braking system is not working correctly. You can continue driving if it lights up but it is best to take it to a mechanic to check the problem.


This amber colored light comes on when the stability control works. Many times it comes on when the ABS is not working properly. In this case, you have to stop sending power to the wheels to regain optimal traction. In many cars it can be deactivated, so it will stay on.


Another of the best known by drivers. The amber fuel light comes on when the fuel level is low and you have to start considering stopping to refuel. Each car has a different tank and, therefore, a reserve with a greater or lesser capacity. When it lights up, it begins to circulate in reserve and you have 50 to 100 kilometers to make the stop.


The amber light on the bulb comes on when a light bulb has burned out and requires replacement. Newer cars can indicate which one is affected, but the best way to identify it is to get out of the car and look.


On models with an automatic gearbox, this light appears to instruct the driver to depress the brake pedal before moving the mode shift lever. When the change is being made with the pedal depressed, the indicator lights green.


The pilot of the start-stop system works in a similar way to that of the airbag, for example. Many new cars have this starter system, which can be deactivated on a voluntary basis. In this case, when the system is disconnected, the pilot will always be on. When it does not work properly it will also light.


It is a delight to drive on the motorway, setting the car at 120 km / h and maintaining the speed without the need to give gas. This light will turn green when the system is activated to remind the driver that it is being used.
