What are the warning lights on the car dashboard?

Car dashboard warning lights include: engine oil warning light, coolant temperature warning light, tire pressure warning light, battery warning light, and electronic stability control (ESC) indicator. The engine oil warning light often indicates low oil level, which is relatively simple to address by adding oil, and car owners can handle it themselves. The coolant temperature warning light typically signals overheating. When the coolant temperature in the radiator reaches 100°C while driving, this light will illuminate. If the tire pressure warning light comes on, it's important to determine whether the pressure is too high or too low. Excessive pressure can lead to tire blowouts while driving, so the tire pressure should be reduced. The battery indicator displays the working status of the car battery and is usually red or yellow in color. When turning the key for a self-check, this light will turn on and should automatically turn off after starting the car. The ESC indicator shows the working status of the electronic stability control system and is typically yellow. Normally, this light is off. If it stays on, it may indicate that the ESC system has been turned off, usually due to accidental operation by the driver.
There are quite a few warning lights on the dashboard, with the most common being the engine warning light. When it lights up while I'm driving, I need to be cautious about potential engine issues—it could indicate problems with the fuel system or sensors, and it's best to get it checked. The battery indicator light signals a charging system malfunction; ignoring it could lead to a breakdown. The oil pressure light is even more critical—if it comes on, it means the engine is low on lubrication, which can reduce performance or, in severe cases, destroy the engine. I once ignored it and ended up spending a lot on major repairs—totally not worth it. If the ABS light stays on, it affects the anti-lock braking system, increasing risks when driving in the rain. Most cars now come with a tire pressure warning light, alerting you to low tire pressure, which can lead to blowouts at high speeds. The airbag light indicates a problem with the safety system, meaning it won't deploy in an emergency. These lights are your car's lifelines—don't wait until disaster strikes to regret ignoring them.
There are quite a few warning lights, and as a long-time driving enthusiast, the ABS light is the one I see most frequently. When it comes on, the anti-lock braking system may fail, making the tires prone to locking up and skidding during braking. When the check engine light illuminates, I immediately think there might be an issue with the exhaust or control unit. Modern cars can read fault codes through the OBD interface, making it easier to diagnose initially. The battery indicator light signals insufficient charging, and neglecting it can affect all electronic devices. The tire pressure monitoring light is crucial for preventing blowout accidents, and I always carry a portable pump to top up the tires when needed. If the airbag light comes on, it's a serious matter as the airbags might not deploy in a collision. There's also the temperature warning light; if it indicates overheating, you need to stop and let the engine cool down, or risk severe engine damage. Regularly checking these lights ensures driving safety.
