What do the lights on the dashboard of a car stand for?

There are many kinds of indicator lights on the dashboard, and the types of indicator lights are different with different vehicle configurations. Generally, the higher the configuration, the more indicator functions there are, and the indicator lights on the dashboard of various brands of cars are different. It depends on the product manual, such as seat belt alarm, high temperature of tank oil and low tank oil. Rare alarms like engine alarms need attention. You should go to the repair shop to check whether it is a spark plug. Some are so many that you don't know what it means, and some are so few that you can't count them.

So it's not easy to make it clear. Lights and other indicators are pre-school education, and all cars have them. As long as I pass the theoretical test in the driver's license test, I won't say anything, only the fault light, which is directly related to driving safety. I think the key points are as follows:

Common fault lights are divided into yellow and red colors according to colors. Yellow means there is a problem, but it will not affect safety. For example, the engine fault light indicates that there is something wrong with the emission control system, and the exhaust gas may not meet the standard, but it will not directly affect the driving safety (as long as it is not scared). For example, the oil pressure light, high temperature warning light, battery indicator light, gearbox oil temperature warning light and door half-open indicator light are basically red, because they are all on, indicating that the problem is serious. Of course, this is only a general statement, and the specific situation should be judged according to the actual situation. For example, some car water temperature lights, ABS lights and airbag lights are yellow and red, but ABS problems will indirectly affect safety. Also pay attention to the handbrake light. Some cars will turn on the handbrake light when the brake oil level is low, but the owner may think that the handbrake switch is broken, so be sure to pay attention when turning on this light.

Different manufacturers have different shapes of indicator lights, so the best way is to read your user manual.
