When to Turn on the Hazard Warning Lights?

[Gray]

The hazard warning lights should be turned on when the vehicle breaks down and requires rescue. The method to turn on the hazard warning lights is to press the red triangular button on the vehicle's dashboard. The functions of the hazard warning lights are: 1. To alert other vehicles in case of breakdowns, accidents, or other emergencies; 2. To prevent rear-end collisions when parking on the roadside. The maintenance methods for car lights include: 1. Check the sealing of the headlights and replace the sealing ring between the lens and the reflector if damaged; 2. Clean dust and dirt on the bulb with alcohol-soaked cotton swabs, and let it dry naturally without touching the bulb with hands or cloth; 3. Clean the reflector: Use clean cotton dipped in hot water to clean, avoiding wiping to prevent damage to the reflector coating.
