What does it mean when the small sun light on the car is on?

[StHeidi]

The small sun light on the dashboard staying lit indicates a bulb fault warning light, which means there is a lighting alarm. It suggests that a bulb somewhere in the vehicle is damaged, reminding the owner to check all the vehicle's lights. Typically, the light will turn off after the bulb is replaced. Below is relevant information: Bulb Fault Light: The bulb fault light is shaped like a small sun and generally indicates that a bulb in the vehicle is faulty. Common lights include turn signals, brake lights, license plate lights, marker lights, front and rear fog lights, reverse lights, high beams, and low beams. Cause: If all the vehicle's lights are checked and no faults are found, but the small sun light remains lit, it may be due to a loose connection in the wiring, poor wiring, or a bulb filament that is partially broken.
