The Color and Meaning of Light Failure Warning Lights
2 Answers
Light failure warning lights are generally categorized into three types: indicator, reminder, and warning. Detailed analysis: 1. Indicator: The most commonly seen while driving, such as turn signal lights, light indicators, seat belt indicators, cruise control indicators, and parking indicators, fall into this category. 2. Warning: Examples include fuel level indicators or windshield washer fluid level indicators. These lights warn the owner that the corresponding fluid needs to be replenished as soon as possible. 3. Fault: This includes engine (exhaust system) fault lights, oil system fault lights, battery and charging system fault lights, etc. These fault indicators rarely light up under normal circumstances, but if they do, it indicates that the vehicle has already developed a fault or abnormality.
When that yellow light comes on, I know there's an issue with the lighting system—usually a burnt-out bulb or circuit malfunction. Having driven for over a decade, I've encountered it several times. The indicator is typically amber or yellow, resembling a small bulb icon. It signifies a defect in the exterior lighting system, such as a short circuit or poor contact in headlights, turn signals, or brake lights. Upon noticing it, it's best to pull over and inspect immediately—otherwise, driving at night makes your vehicle less visible to others, increasing accident risks. I once experienced a minor rear-end collision due to a faulty taillight. My advice: regularly check all lights. Replacing bulbs yourself isn't hard, but it's safety-critical—don't delay. If unsure, visit a professional shop to avoid fines.
