What does it mean when a red light on the car dashboard is on?

When a red light on the car dashboard is illuminated, it indicates that the anti-theft system is activated. If the car door is not properly closed and cannot be locked, the hazard warning lights will flash. Below is additional information: 1. Car Dashboard: The door status indicator light shows whether the doors are fully closed. When a door is open or not properly closed, the corresponding indicator light will illuminate, alerting the driver that the door is not shut properly. The light turns off once the door is closed. 2. Parking Brake Indicator: This light turns on when the parking brake handle (i.e., handbrake) is pulled up. The light automatically turns off when the handbrake is released. In some car models, this light may also illuminate when the brake fluid level is low.
Having driven for many years, I know that a red warning light on the dashboard is no joke. Red lights usually indicate serious issues, such as low oil pressure leading to insufficient lubrication, which can cause engine overheating and damage; or problems with the braking system, posing a high risk of hydraulic failure. Other scenarios include overheating coolant temperature or alternator failure causing charging interruption. Once a red light comes on, don’t hesitate—pull over immediately and turn off the engine—safety first. Refer to the owner’s manual to identify the symbol and determine the issue: if it’s the oil light, check the dipstick for oil level; if it’s the coolant temperature light, don’t restart the engine until it cools down. Ignoring a red light can lead to much costlier repairs, or even total vehicle failure in severe cases. Develop good habits—check oil and coolant levels monthly, and regular maintenance can prevent many potential hazards.
