What is the flashing light when a motor vehicle malfunctions?
2 Answers
When a motor vehicle malfunctions, the corresponding warning light for the faulty component will flash. However, a lit warning light does not necessarily mean the vehicle cannot be driven. Some lights serve only as warnings, or may indicate false alarms. Common warning lights include: 1. Engine and transmission: Engine malfunction light. 2. Airbag: Airbag warning light. 3. Braking system: Brake system malfunction light. Warning lights can generally be categorized into three types based on the cause of illumination: 1. False alarms: The warning light is on, but there is no actual malfunction with the vehicle. 2. Intermittent faults: The warning light flickers on and off, indicating an intermittent issue. Examples include loose sensor wiring, poor connector contact, or intermittent signal transmission. 3. Genuine faults: These require immediate attention when the warning light is illuminated, such as the oil pressure warning light, coolant temperature indicator, brake system malfunction light, or battery warning light.
When a car breaks down on the road and can't move, that flashing light is called the hazard warning lights or emergency flashers. Simply put, it makes the front and rear lights flash together to warn others of an emergency. During my long-distance drives, I've encountered a few minor incidents like flat tires or engine stalls, and the first thing I did was press that red triangle button to turn them on. This way, other drivers see the flashing lights and will slow down or steer clear, avoiding chain collisions. According to traffic regulations, hazard lights must be turned on when stopping due to a breakdown on the highway, otherwise, you may face fines or penalty points—it's a lifesaving measure. Some new cars even have an automatic sensing feature that activates the hazard lights when the system detects emergency braking, but don’t rely solely on it—manual operation is the most reliable. Remember, after turning them on, you should also place a warning triangle behind the car for added safety. In short, this simple feature has saved many lives, and it’s best to make it a habit.
