Ignition of any warning light must be treated with the utmost seriousness by each driver, as this indicates an electrical or mechanical failure of the car, wear and tear of various parts or certain errors.
Before you know the meaning of each sign on board, you need to understand their color classification. Here are the three types of on-board witnesses and what each of these categories means.
If you are a driver, you have probably noticed the warning lights coming on when you start the car and you have noticed that they are arranged in three categories, each with its own color. The reason why the light signals are distributed in this way is very simple, and each category announces a certain type of problem. Thus, an on-board witness may be:
Red – Announces a serious car failure or a safety issue that requires immediate attention from the driver.
Yellow – (or orange, as appropriate) – A malfunctioning component that needs to be replaced. Depending on the type of light bulb on board, the fault may need urgent or delayed repair, but only for a few days.
Green – (or blue, as appropriate) – Informs you about the status of a car component.
