What does it mean when a car's warning light comes on?

[EloiseFitz]

When a car's warning light comes on, it depends on which indicator light it is. If it's the engine warning light, it indicates an issue with the engine; if it's the bulb failure warning light, it means a car bulb is damaged and needs replacement; if it's the tire pressure warning light, it suggests there's a problem with the tire pressure, etc. Below is some relevant information about warning lights: 1. Warning lights are indicators on the car that alert the owner when a certain part of the vehicle has a fault, signaling that the relevant part is in an abnormal state and requires immediate attention. Different faults have different colored warning lights, so it's important for the owner to fully understand the meanings of the respective warning lights. 2. When a vehicle's warning light comes on, the owner should promptly inspect the relevant part and carry out repairs. Some warning lights indicate faults that won't affect normal driving, while others might. To ensure driving safety, it's recommended that the owner addresses the issue promptly.
