What Does the Light on the Vehicle Dashboard Indicate?
3 Answers
The light on the vehicle dashboard is a display or record of the current state of the vehicle, serving as a reminder to the driver. Therefore, the most crucial step is to first determine whether these states represent normal conditions or indicate a problem, and to understand the severity of the issue and the corresponding alert level. This way, you can take appropriate action promptly when the dashboard light illuminates. Here’s a detailed introduction: Dashboard lights in vehicles are generally categorized into green, blue, orange/yellow, and red. These four colors correspond to risk levels, arranged from low to high: 1. Green: When a green dashboard light comes on, there’s usually no need to worry in most cases. Like a traffic signal, green indicates normal operation. 2. Yellow or Orange: When this type of dashboard light illuminates, it generally indicates an issue with a certain function or state of the vehicle, requiring corresponding attention. However, in most cases, it’s not urgent enough to require immediate resolution. 3. Red: When this type of dashboard light comes on, never take it lightly. It either signifies a significant problem with the vehicle’s condition or a safety hazard for the occupants. For example, the warning light for the handbrake being engaged or the seatbelt not being fastened is a bright and conspicuous red.
The day before yesterday, I encountered a dashboard warning light issue and immediately pulled over to check. Actually, different colored lights on the dashboard indicate varying levels of urgency. Red lights, such as the oil pressure warning or coolant temperature alert, require immediate stopping and inspection, as continuing to drive could damage the engine. Yellow lights, like the engine malfunction indicator, allow for short-distance driving, but you should visit a repair shop to read the fault codes as soon as possible. Green lights are mostly status indicators, such as parking lights or low beam activation prompts, which are nothing to worry about. I later found out that insufficient engine oil was the main cause, and adding a liter of oil made the light disappear. I recommend new car owners take a photo of the warning light icon to help mechanics quickly identify the problem.
Having been in transportation for twenty years, I dread seeing the dashboard suddenly light up red. The brake system warning light indicates a problem with braking power; continuing to drive may lead to brake failure. The oil pressure light flashing means the lubrication system is faulty, and the engine could seize at any moment. A constantly lit battery light means the alternator isn't generating power, and the vehicle will lose all power in at most twenty minutes. Yellow lights, like the ABS light, mean you can still drive, but braking in the rain can easily cause skidding. Once, my apprentice ignored the coolant temperature warning light, and the cylinder head ended up warping. Remember the rhyme: Red light means stop, yellow light means repair, green and blue lights are no worry.
