However，Not all the warning lights distributed on the instrument panel refer to fault lights，They can be roughly divided into three categories:Indicator lights, warning lights, fault lights.Usually these indicator lights vary according to the risk factor，also divided into green、黄、Red three colors (applicable to most models)，When the red light comes on, it is best for the driver to stop immediately。

As for which fault lights are most dangerous when seabet loginthey are on，Some experienced drivers said:As long as the water temperature and oil indicator light does not light up, it is basically fine to drive it for another half a year。Indeed，What a car engine fears most is lack of water、Lack of oil，The water temperature fault light is equally dangerous as the oil fault light.。

Among them，The water temperature indicator light is used to display the circulating temperature of the coolant in the vehicle engine，When the vehicle is started for self-test，The water temperature indicator light will light up，If the water temperature is normal，It will automatically turn off after starting。But after startup，The water temperature indicator light is still on，Two situations will occur:Bright blue light indicates the water temperature is too low；A bright red light indicates that the water temperature is too high。

When encountering this situation, you can take the following countermeasures:When the water temperature is not high，Stop and check whether the coolant level is normal、Pinch up the water pipe and look at the pressure gauge (to avoid inaccurate water temperature gauge)，If the coolant is insufficient, replenish the coolant after cooling and drive to the repair shop for inspection。If there is enough coolant，Water temperature gauge is normal，The water pipe pressure is not high，You need to go to the repair shop for inspection。If the water temperature is too high，You need to cool down and then drive slowly to the repair shop or contact rescue。

The oil pressure indicator light is the same as the water temperature indicator light，When the vehicle is started，The lamp will light up，If the oil pressure is normal，The indicator light then goes out，But if it stays on, it means the engine oil pressure seabet loginis too low or the fluid level is too low，Stop the vehicle immediately and turn off the engine。

Everyone knows，Motor oil is the "blood" of the engine，If something goes wrong, continue driving，Can cause the engine to lose lubrication，Severe wear and tear。At this time，What car owners should do is: check the oil level through the oil dipstick，If the level is too low，Please replenish engine oil immediately，If the fault light does not go away after adding engine oil，Please do not start the vehicle，Contact rescue as soon as possible。

Actually，Except water temperature fault light and oil pressure fault light，ABS anti-lock braking system fault light、Power steering warning light、Tire pressure warning light、The engine indicator light is equally important，Once they light up，Don’t just sit back and do nothing，Check it yourself、Go to the nearest repair shop，Or call for rescue，We must find the reason，Please wait until they turn off before continuing to ride。

What needs to be explained is，The engine fault light stays on，It may also be a false fault。This may be an operation beyond the control of the computer，Fault code reported by the computer。Car owners can remove any binding wire from the car battery，Reconnect the battery after more than ten seconds，After starting the car，If the fault light disappears，That means there is no problem with the engine。

In short，You should be concerned about every indicator light on your car，But when the 6 indicators mentioned in this article are on，Be sure to pay special attention。
