The yellow sun-shaped light on the dashboard is a lighting warning light, indicating a bulb fault light. It signifies that a bulb somewhere in the vehicle is damaged, reminding the owner to check all the vehicle's lights. Possible causes include loose wiring, poor connections, or a bulb filament that is partially broken. It is essential to promptly visit a repair shop to inspect the wiring or replace the bulb to avoid traffic accidents. Automotive lights mainly include: headlights (high beam and low beam), front position lights, rear position lights, license plate lights, instrument panel lights, turn signals, brake lights, hazard warning flashers, reverse lights, front fog lights, etc. High beams are crucial for illuminating the road ahead and providing a warning function. They help observe pedestrians at night when visibility is low. Low beams, on the other hand, are designed for close-range illumination, covering a wide area but with a shorter distance (about 30-40 meters). In urban or high-traffic areas, it's best to use low beams at night to avoid blinding other drivers or pedestrians with the intense light of high beams. Rear lights serve as a warning to other vehicles, especially at night when external lighting is poor. They help prevent accidents by alerting following vehicles, ensuring safer nighttime driving. Interior lights provide illumination inside the car, making it easier to see objects during nighttime driving. Turn signals are used when making turns, serving as a warning to other vehicles to prevent accidents. Using turn signals while turning enhances driving safety and reduces the likelihood of mishaps.
