The information about car warning lights is as follows: Tire Pressure Warning Light: A yellow symbol featuring an irregular circle that is open at the top, with four small spikes at the bottom and an exclamation mark inside. When this light appears, it indicates abnormal tire pressure, and the tires should be checked promptly. Engine Coolant Temperature Warning Light: This light usually stays on when the car is first started, especially in winter. It has a blue thermometer-like design and illuminates when the engine coolant temperature is too high or too low. Some vehicles may have a temperature gauge on the dashboard, with a needle that rises or falls according to the coolant temperature. Oil Pressure Warning Light: This is an icon on the dashboard shaped like a "kettle." It lights up when there is an abnormality in oil pressure. The oil pressure warning light turns on when the vehicle starts. If the oil pressure is normal, it will turn off shortly after. If there is an issue with oil pressure, the light will remain on. Battery Warning Light: During driving, the battery is a crucial component. If there is a problem with the battery, it can lead to issues while driving the car.

I've been driving for almost twenty years, and it's essential to recognize those warning lights on the car dashboard. The common engine malfunction light is a yellow or red light—if it turns on, there might be an issue with the fuel system or sensors. The oil pressure warning light indicates insufficient lubrication, which can cause rapid engine wear. The ABS light signals a fault in the anti-lock braking system, potentially affecting braking performance. Many cars now have a tire pressure monitoring light that activates when tires are underinflated. The airbag warning light relates to the safety airbag system and should never be ignored. The battery warning light points to charging system problems, which could leave you stranded. Additionally, if the coolant temperature light comes on, you should stop the car immediately. Regular maintenance checks on these lights and timely action can help avoid major repairs.

As someone who repairs cars every day, I've dealt with all kinds of warning lights. The engine warning light is the most common, and the OBD system can read specific trouble codes; the oil light indicates low oil pressure, requiring immediate oil top-up or pump inspection; the ABS light often comes on due to dirty wheel speed sensors or wiring issues; the airbag light relates to the airbag module and requires professional diagnosis; the tire pressure light is now standard equipment, helping prevent blowout risks; the brake warning light signals the need to check fluid levels or pad wear; the battery warning light indicates alternator or battery failure; others include the temperature warning light and door ajar light. A tip is to perform regular full-vehicle scans to prevent potential hazards from turning into accidents.

When I first started learning to drive, I would get nervous whenever a light came on. That yellow check engine light indicates an engine problem; the oil pressure light looks like an oil can icon and may mean the oil level is too low; the battery warning light resembles a small battery, signaling a charging system fault; the ABS light is related to the braking system warning; the airbag warning light indicates an issue with the safety system; there's also the tire pressure monitoring light, which reminds you to inflate the tires; and the seatbelt indicator always urges me to buckle up. It's important to remember the meanings of these lights. Now I always carry the manual with me, so I don't panic when something happens.

Why do the car lights stay on after the engine is turned off?

The ACC control wire was probably not connected during installation. The aftermarket LED daytime running lights are not part of the original vehicle system and cannot be controlled by the onboard computer. If the ACC control wire is connected, the daytime running lights will turn on when the vehicle's ACC is working and turn off when the engine is shut down. Without the ACC control wire connection, the daytime running lights are controlled by the power supply voltage. Additional information: Enhancing headlight brightness improves driving safety. As spring arrives, increasingly frequent rainfall exacerbates the situation for drivers who already find their headlights insufficiently bright. Rain reduces the penetration of light, and the high reflectivity of wet roads creates significant visibility challenges for nighttime driving.
